A Hidden Treasure. Church of St Stephen in Nessebar

The Church of St Stephen in Nessebar, a town situated on Bulgaria’s Black Sea coast, also known as the New Metropolis, is a precious monument of medieval ecclesiastical architecture.

I ended up in Nessebar somewhat by chance, en route to Istanbul. A friend of mine runs a travel agency that specialises in unusual destinations. He had come up with the idea of a late autumn stay in Golden Sands, Bulgaria – where it was still warm enough for me to swim undisturbed in the hotel pool – with a two-day coach trip to Istanbul as part of the itinerary. I knew virtually nothing about Nessebar beforehand.

After about half an hour of wandering through a nice looking old town, we stepped into this small church – and, to put it plainly, my jaw dropped. Unlike many other churches I’ve seen in recent years, this one hadn’t been fully restored. Instead, what remains from the past has been carefully preserved as it is. Coming from a country where so much was destroyed in wars – where what we see today is often a reconstructed version of the original – I’ve come to truly value places that have retained their authentic character. There’s something deeply moving about standing in a space where the passage of time is visible, not hidden, but you still see the past.

Originally founded by the Thracians as Menebria, Nessebar was taken over by Greek settlers from Megara in the 6th century BC, who renamed it Mesembria. It later flourished as a major port under Roman rule and became an episcopal centre within the Byzantine Empire. During the Middle Ages, the city was incorporated into the Bulgarian state and emerged as a key strategic stronghold, frequently passing between Bulgarian and Byzantine control. Since antiquity, Nessebar’s prosperity has been rooted in maritime trade.

Then, for nearly five centuries – from 1453 onwards – the city remained under Ottoman rule. In the early years of this period, Nessebar attempted to preserve its identity through the strength and vitality of its Christian community. However, over time, the city lost its political and military importance, the port declined, and Nessebar gradually became a quiet fishing and farming settlement. Yet even as its prominence faded, the town acquired a distinctive architectural legacy. The 18th and 19th centuries saw the construction of characteristic stone-and-wood houses, with solid masonry bases and timber-framed upper storeys that overhang the narrow cobbled streets – a modest but enduring expression of the Bulgarian Revival style.

Deprived of major investment and largely bypassed by modern infrastructure, Nessebar changed little for decades, preserving much of its historical character just so. Nessebar was restored to Bulgarian control in 1885, following the unification of the Principality of Bulgaria with the autonomous province of Eastern Rumelia, of which it had been a part after the Russo-Turkish War. However, the absence of a direct railway connection and the town’s relative isolation slowed its development. It was not until the 1920s and 1930s that Nessebar’s exceptional historical and architectural value began to be widely recognised.

Archaeologists and historians began to document and study Nessebar’s churches, city walls and Byzantine-era monuments in greater depth, and the first conservation efforts were launched in 1934. After 1945, the town began to attract growing numbers of visitors, drawn by both its historical significance and its coastal setting. In 1956, Nessebar was officially declared an architectural and archaeological reserve of Bulgarian national importance. This recognition culminated in 1983, when the Old Town was inscribed on the UNESCO World Heritage List. Adding to its appeal is the fact that several of the country’s largest seaside resorts — including Golden Sands — are located nearby, making Nessebar a popular cultural destination for holidaymakers visiting the region for sun and leisure.

Since antiquity, Nessebar has been renowned for its remarkable concentration of historic churches and a strong Christian presence. Christianity reached the city in the early centuries AD. As a prominent trading port on the Black Sea, Nessebar maintained close contact with both the Greek and Roman worlds, which facilitated the spread of new religious ideas. During the Roman Empire the first Christian communities began to form. Following the Edict of Milan in 313, which legalised Christianity across the empire, the Church developed rapidly. By the 4th or 5th century, Nessebar had already become the seat of a bishopric. It was around this time that the first significant churches were constructed, and Christianity gradually became the dominant faith in the city. The participation of Nessebar’s bishops in major councils of the Eastern Church further affirmed its role as an established Christian centre. Among the most significant and best-preserved churches in Nessebar is the Church of Saint Sophia (known as the Old Metropolis), dating back to the 5th–6th century (compare photos below).

During its period of greatest prosperity – especially under the Byzantine Empire and the Second Bulgarian Kingdom (10th to 14th century) – the Christian community played a central role in urban life. The city not only remained a bishopric but was later elevated to the status of a metropolitan seat. Its ecclesiastical leaders maintained relations with key religious centres of the Byzantine world, and their presence fostered spiritual growth and reinforced the city’s status in the region. Perhaps the most visible sign of this religious vitality was the sheer number of churches. In the Middle Ages, Nessebar could boast several dozen, some of which survive today. Built in the Byzantine and Bulgarian styles, many of these churches were commissioned by wealthy patrons – merchants, nobles, and dignitaries. The elaborate decorations – frescoes, mosaics, and iconostases – reflected the city’s high artistic standards and its role in the development of sacred art. Attached to many churches were schools where literacy and the copying of liturgical texts were taught. Monks and clergy were more than spiritual leaders – they also served as educators, caretakers of the poor, organisers of communal life, and guardians of tradition.

This deeply rooted Christian life suffered a marked decline after 1453, when Nessebar fell under Ottoman rule. The Ottomans did not destroy the churches nor ban Orthodox worship, but the Christian population, as a subordinated group, faced legal restrictions and special taxation. Many churches fell into disrepair or ceased functioning altogether, as the Christian community dwindled and its financial means diminished. Nonetheless, religious life did not disappear entirely. In some churches – such as St Stephen’s – frescoes from the 16th and 18th centuries survive, bearing witness to the continued use of these spaces even in challenging political conditions. Following Bulgaria’s liberation from Ottoman rule and Nessebar’s formal return to Bulgarian control in 1885, the Christian community began to revive, albeit slowly. Churches were gradually reclaimed – some restored, others converted into museums to preserve their legacy.

Today, although many of Nessebar’s churches have museum status, several, including the Church of St Stephen, are still occasionally used for religious services, offering a living link to the city’s enduring spiritual heritage. Of course, there are also churches in Nessebar that continue to serve fully as active places of worship, even though they remain open to visitors. I’ll show one of these in a post.

The Church of St Stephen in Nessebar is quite small, and from the outside – especially to someone not versed in ecclesiastical architecture – it wouldn’t necessarily be recognised as a church at all. It’s enclosed by a low stone wall, and scattered around it are fragments of an earlier structure, likely parts of the original building that haven’t survived intact. When you step inside, the space is lit by old chandeliers suspended from the ceiling, which provide the main source of light. You can clearly see that the most of the ceiling is made of new wood. Some additional sources of light are attached to it. In areas where their glow doesn’t quite reach, a freestanding spotlight is used to offer additional illumination. Heaters or air conditioning units help maintain a stable indoor temperature. According to our guide, this is essential for preserving the frescoes and interior structure. The system is powered by wiring run externally, so no alterations have been made to the church’s original construction.

The building was constructed between the 11th and 13th centuries as a three-nave basilica, with the central nave rising higher than the side aisles, measuring approximately 12 by 9.5 metres. In the 16th century, it was extended westwards, and in the 18th century, a wooden entrance vestibule was added. Built of stone and brick, the church has a modest yet carefully composed structure. Embedded in the walls are spolia – architectural elements reused from earlier buildings – including stone cornices, column capitals, and relief fragments, most likely originating from ancient Roman or early Byzantine temples.

One of the most distinctive features of medieval architecture in Nessebar, including the Church of St Stephen, is the use of the opus mixtum technique, a building method that became common in the Byzantine world from late Antiquity through the Middle Ages, particularly between the 10th and 14th centuries. This technique involves alternating layers of stone and brick, creating a visually striking texture on the façades. It served not only as a decorative feature – it also had a stabilising function, helping to reinforce the structure on the marshy ground of the island. In Nessebar, bricks of varying colour and shape were not only functional but also served a decorative purpose, forming intricate patterns and ornamental designs on exterior walls. This method reflects the influence of the Tarnovo School of Architecture, which flourished in the Second Bulgarian Empire, centred around the medieval capital Veliko Tarnovo (historically known simply as Tarnovo). This style is renowned for its richly detailed façades, often incorporating glazed ceramic elements in tones of green, brown, yellow and orange, adding both colour and symbolic meaning to sacred buildings.

Inside, the structure of the building becomes immediately clear: a three-nave basilica layout, with the central nave slightly higher and more prominent than the side aisles – a typical feature of Byzantine ecclesiastical architecture. Just beyond the entrance, one notices a wooden pulpit dating from the 18th century, modest in size but rich in character, showing visible signs of age. It stands on the left side of the nave with its carved details and iconographic panels reflecting the craftsmanship of the period. On the right side there is the bishop’s throne, dating also from the 18th century, which – along with the pulpit – forms part of the preserved liturgical furniture .The three naves gradually lead towards a more enclosed space, culminating in a wall that separates the main area of the church from what lies beyond – a characteristic feature of Orthodox churches, where the iconostasis forms both a visual and symbolic boundary between the congregation and the sanctuary hidden behind it, where the altar is located. In the Church of St Stephen, the iconostasis is a finely carved, three-tiered wooden screen, adorned with icons and decorative motifs – one of the most artistically significant elements of the interior.

The interior of the Church of St Stephen in Nessebar contains some of the most valuable late medieval frescoes in Bulgaria. In 1599, during the time of Metropolitan Christophor of Nessebar, three painters created a total of 258 wall compositions, depicting over 1,000 individual figures. The frescoes illustrate scenes from the life of the Virgin Mary, the miracles of Christ, and the Last Judgement. A later depiction of the Last Judgement, located in the narthex and painted in the 18th century, was executed in a more theatrical style, featuring dynamic figures and elaborate scenography. In addition to the main cycles, the programme includes less commonly represented themes, such as the Cycle of Joachim and Anna (Mary’s parents) and miracles performed by lesser-known saints, adding iconographic richness to the interior. Stylistic analysis indicates that the work was divided among three artists. Two of them painted the eastern part of the naos, displaying a higher level of precision and decorative detail, while the third, responsible for the western section, adopted a simpler and more narrative approach to composition. The frescoes were executed using the al fresco technique, with pigments applied directly onto fresh lime plaster. The colours, derived mainly from natural mineral sources, have retained much of their original vibrancy over the centuries.

What remains in memory is the stillness, the dim light, and the walls that seem to speak in colour. A church that quietly holds centuries – and lets you glimpse them.

The Holy Spirit Church of Vilnius

Normally, on this blog, I tend to showcase various Catholic or Protestant churches. However, during a few of my recent travels, I had the opportunity to visit several Orthodox churches — and, on some occasions, even take photographs inside. Sometimes photography was prohibited, but if you refrained from using flash and took respectful pictures rather than selfies, there was often a quiet acceptance that allowed visitors to capture a few images.

Today, I would like to share a glimpse of an Orthodox church that you would hardly notice from the street, though it is not particularly difficult to find. It is the Church of the Holy Spirit in Vilnius. If you enter the Old Town through the Gate of Dawn (the one above which the Chapel of Our Lady of the Gate of Dawn is located), walk a short distance straight ahead, pass another church on your right-hand side, and a few step further you will see a gateway. This leads into a courtyard or garden area, where the Church of the Holy Spirit is situated.

Although this church is not lavishly decorated compared to grand Orthodox cathedrals, it possesses a quiet and distinctive charm. The interior is modest yet captivating, dominated by a vibrant three-tiered wooden iconostasis richly adorned with carvings and gilded details, characteristic of the Baroque style. The main altar stands out with its deep green and gold tones, which immediately draw the visitor’s eye. In the centre of the sanctuary, there is a display case containing the relics of the Martyrs of Vilnius — Saints John, Anthony, and Eustathius. The relics are draped in a liturgical vestment and placed under an elegant wooden canopy, richly decorated with carved ornaments and small hanging incense burners. This arrangement enhances the sacred and intimate ambiance of the space. The walls are lined with traditional Orthodox icons, including one particularly striking image depicting two female saints (likely St. Barbara and St. Catherine). Despite its simplicity, the Church of the Holy Spirit leaves a powerful impression as you can see on the photos.

The Church of the Holy Spirit in Vilnius takes its name from the Holy Spirit, the third person of the Holy Trinity in Christian theology, symbolising divine presence and inspiration. The original church on this site was a wooden structure built in 1638. After a fire in the 18th century destroyed the building, the current stone church was constructed between 1749 and 1753 under the supervision of architect Johann Christoph Glaubitz.

The Church of the Holy Spirit is particularly revered as the resting place of the Martyrs of VilniusSaints John, Anthony, and Eustathius. According to tradition, these three men served as courtiers at the court of Grand Duke Algirdas of Lithuania.

In the 14th century, when Grand Duke Algirdas ruled Lithuania, the country was officially pagan. However, Algirdas was married to a Christian princess — Princess Juliana (or Maria), who was Orthodox and came from Novgorod or the Rus lands. Thanks to this union, there was a degree of tolerance towards Orthodoxy at the ducal court, at least in private life. It was in this environment that a number of courtiers, including John, Anthony, and Eustathius, came into contact with Orthodox Christianity. They grew interested in the new faith and were baptised most likely under the influence of the Grand Duchess’s entourage or the Orthodox clergy present at the court.

Although Algirdas was personally tolerant of different religions, Lithuania as a state remained formally pagan. When these three courtiers converted to Orthodox Christianity, they broke the official religious norm at court. This act was perceived as a threat to the unity and security of the pagan state, rather than merely a personal religious choice. Consequently, they were pressured to revert to paganism. Their refusal to abandon their new faith led to their execution around the year 1347. The martyrs’ bodies were buried at or near the place of their execution, and were soon venerated by the faithful.

With the consolidation of Christianity in Lithuania after 1387 and the growth of the Orthodox community in Vilnius, the relics were transferred to the city’s main Orthodox church — the Church of the Holy Spirit. The final translation of the relics occurred in 1581, when they were placed in a special chapel within the Church of the Holy Spirit, inside an ornate reliquary. Despite numerous upheavals — the partitions of Poland, Tsarist rule, and the Soviet era — the relics have survived. Today they are enshrined in a display case at the centre of the sanctuary. The relics are draped in vestments of different colours according to the liturgical calendar: black during Lent, white at Christmas, and red on major feast days, reflecting the solemn or festive nature of each liturgical season.

Another significant historical aspect of the Church of the Holy Spirit is that, unlike many other Orthodox churches in this region, it was never handed over to the Uniate Church (Greek Catholic Church). To understand the importance of this, we must delve deeper into the religious history of this part of Europe. In 1569, the union was concluded between the Kingdom of Poland and the Grand Duchy of Lithuania, creating a single state — the Polish–Lithuanian Commonwealth — which also encompassed vast territories of what is now Ukraine, Belarus, and parts of Latvia.

Poland had adopted Catholicism as early as 966, when Duke Mieszko I was baptised along with his court according to the Latin rite (Roman Catholicism). This was a deliberate political move: Poland chose to align itself with Western Christianity (Latin culture, Rome) rather than the Eastern Orthodox Christianity (Byzantine culture, Byzantium, Eastern rite). From that moment, Poland remained a Catholic country, although other denominations (such as Protestantism in the 16th century) later appeared.

Lithuania, in contrast, was the last pagan state in Europe and did not officially embrace Christianity until 1387. However, even before its official baptism, Lithuania controlled vast Ruthenian territories (modern-day Belarus, Ukraine, and parts of Russia), where the population had been Orthodox Christian since the 11th century. Thus, while ethnic Lithuania (the Baltic tribes) remained pagan, many of its subjects in the eastern lands were already Orthodox.

The fusion of these traditions was sealed when Grand Duke Jogaila (later Władysław Jagiełło) accepted Catholicism in 1386 to marry Queen Jadwiga of Poland, subsequently becoming King of Poland. In 1387, he baptised the ethnic Lithuanians according to the Latin rite. As a result, the Lithuanian elites and ethnic Lithuanians became Catholic, while the eastern regions of the Grand Duchy (what is now Belarus and Ukraine) remained Orthodox.

In 1596, following the establishment of the Polish–Lithuanian Commonwealth (a deeper union between Poland and Lithuania), a portion of the Orthodox bishops accepted the authority of the Pope, creating the Greek Catholic (or Uniate) Church. A widespread effort began to subordinate Orthodox communities to this new ecclesiastical structure, often through administrative and political pressure. Many Orthodox churches, especially in towns and villages, were converted to the Uniate Church, losing their original affiliation. However, the Church of the Holy Spirit, as one of the main centres of Orthodoxy in Vilnius, successfully resisted these pressures and retained its unbroken affiliation with the Orthodox Church.

Today, the Holy Spirit Church remains the principal Orthodox church in Lithuania and maintains close ties with the adjacent Orthodox Monasteries of the Holy Spirit and Saint Mary Magdalene. The church serves as the Metropolitan Cathedral.

The Uspenski Cathedral of Helsinki

So far on this blog, I’ve shown the interior of only one Orthodox church (Suprasl Monastery), though in recent years I’ve managed to photograph several others. It is time to bridge this gap.

Eastern Orthodoxy is a branch of Christianity. The official split between Catholicism and Orthodoxy, known as the Great Schism, occurred in 1054. At that time, mutual excommunications were issued between the Patriarch of Constantinople, Michael I Cerularius, and the envoys of Pope Leo IX, who led the Western Church from Rome. The schism arose from growing theological, cultural, and political differences between Eastern and Western Christianity. I’ll likely write a more detailed post on this topic soon, as I recently visited Istanbul (formerly Constantinople) and am currently preparing photos of Hagia Sophia, which, before the city became part of the Ottoman Empire, was the premier Orthodox cathedral

Interestingly, the church I will show today is located in Finland – a country where Lutheranism is the predominant religion, and Orthodoxy has historically been observed by only a small portion of the population. Lutheranism itself separated from Catholicism in the 16th century as part of the wider Reformation movement, led by the German monk and theologian Martin Luther. The Reformation eventually led to the establishment of the Lutheran Church and other Protestant denominations, which permanently altered Europe’s religious landscape. Today, Finland remains largely Protestant, with approximately 65-70% of Finns belonging to the Evangelical Lutheran Church, though that number is gradually declining as secularization continues. The second-largest faith community is the Orthodox Church, comprising only around 1-2% of the population. The remainder of the population includes those with no religious affiliation and smaller religious communities.

Still, the Uspenski Cathedral (Uspenskin katedraali) in Helsinki is one of the largest Orthodox churches in Europe. Situated on the Katajanokka peninsula near the harbour and city centre, the cathedral is built of red brick and features distinctive green domes and golden crosses. At the centre of its interior, we will find the iconostasis, a distinctive feature in all Orthodox churches. This icon-covered wall separates the nave (the space for worshippers) from the sanctuary, where the altar is located. In the central part of the iconostasis are the so-called Holy Doors, which lead directly to the altar located behind them (in the photo, look at the golden cross on the iconostasis). These doors are the holiest part of the iconostasis and are opened only at specific moments in the liturgy, after which they are closed again.

The name Uspenski comes from the Russian and Church Slavonic word Uspenie (Успение), which means Dormition or Falling Asleep of the Mother of God. Essentially, it’s a cathedral dedicated to the Dormition of the Virgin Mary. In Catholic tradition, this event is referred to as the Assumption of the Virgin Mary, a dogma formally declared in 1950 by Pope Pius XII, which teaches that Mary was taken up into heaven, body and soul, at the end of her earthly life. Catholicism thus places emphasis on Mary’s physical ascent into heaven rather than on her falling asleep. By contrast, in Orthodox tradition, the Dormition focuses on Mary’s peaceful transition from earthly life to eternal life.

The Cathedral was built during the reign of Tsar Alexander II, who was known for his relatively supportive stance toward the Finnish people. He was a liberal ruler who advocated for Finland’s autonomy, fostering a period of more harmonious relations between the Grand Duchy of Finland and Russia. His policies were less oppressive, allowing Finns to retain their institutions, language, and culture. Completed in 1868, Uspenski Cathedral symbolised not only the presence of Orthodoxy but also the peaceful ties between Finns and Russians at that time. This situation changed toward the end of the 19th century, however, when the reigns of Tsar Alexander III and Nicholas II brought an era of intense Russification and mounting tensions.

In the 19th century, when Finland was part of the Russian Empire, Orthodox believers comprised as today only a small percentage of Finland’s population – about 1–2%. Lutheranism remained the dominant faith, a legacy from the centuries when Finland was under Swedish rule (until 1809).  With Finland’s incorporation into Russia in 1809, the Orthodox population grew slightly, particularly among Russian officials, soldiers, and merchants who settled in the area. During Russian rule over Finland, particularly in the late 19th century, There were some efforts to promote Orthodoxy among the Finnish population as part of broader Russification policies. While these efforts did not involve forced conversions, they included state support for the Orthodox Church, the construction of new Orthodox churches, and the symbolic elevation of Orthodoxy in public life. Despite these attempts, however, Orthodoxy did not gain significant traction among Finns, who remained predominantly Lutheran and were determined to preserve their distinct culture and religious identity.

The Uspenski Cathedral has retained its original design since its completion in 1868 and has not undergone major structural alterations. The cathedral’s design was created by Russian architect Alexey Gornostayev. After Gornostayev’s death, his team completed the project in line with his original vision. Over the years, the cathedral has undergone only minor renovations and conservation work to maintain its condition. Its characteristic brick walls, green domes, and golden crosses have remained unchanged, allowing the cathedral to preserve its authentic architectural style to this day.

When exploring the interiors of Orthodox churches, it’s useful to recognise two main styles of interior design. Icon-dominant churches: in many Slavic and Balkan Orthodox churches, nearly every surface – walls, domes, and ceilings – is densely covered with icons and frescoes of saints and biblical scenes. Architectural elements like columns and arches serve as supports for the iconography and are less emphasised, allowing the sacred images a visual storytelling. Architecture-integrated churches: in contrast, some Orthodox churches, particularly those in the Russian-Byzantine style – like Uspenski Cathedral in Helsinki – or classic Byzantine structures such as Hagia Sophia, balance sacred imagery with architectural splendour. Here, iconography remains important but is often concentrated on the iconostasis and select areas rather than covering every wall. The architecture itself, with its arches, domes, and play of light, becomes a focal point.

Uspenski Cathedral exemplifies this second style, integrating also distinctive Russian features, such as onion-shaped domes symbolising the flame of faith, intricate cornices and arches that frame the space, and a vibrant colour scheme with red brick, green roofs, and golden crosses.

PS. Helsinki also boasts an impressive Lutheran cathedral, known as the Helsinki Cathedral (Helsingin tuomiokirkko). Located in Senate Square and completed in 1852, is one of the most recognisable buildings and symbols of Finland’s capital.
