A Quiet Encounter with History. Visiting Bari’s Norman-Swabian Castle

Bari is a city in Apulia, southern Italy. I spent a few days there, exploring both on foot and by car, driving in and out through the more modern parts of the city, which gave me a decent overview of its structure. Aside from contemporary districts, Bari it is historic centre, which can be divided into two clearly distinct areas. The first, Bari Vecchia, is the medieval quarter, with narrow alleyways, an old cathedral, and a castle. The second Quartiere Murat features a more neoclassical look, typical of many Italian towns. Its main artery is Corso Cavour, an avenue named in honour of the first prime minister of a united Italy.

Today’s post is dedicated to the castle. It is known as the Norman-Swabian Castle (Castello Normanno-Svevo di Bari), named after its historical ties to two powerful dynasties: the Normans and the Swabians (Hohenstaufen).

The castle was originally built around 1132 by King Roger II of the Normans, on the foundations of earlier Byzantine structures. It was intended to serve as a defensive fortress and a symbol of Norman rule in Apulia. The Normans, who hailed from Normandy in northern France, were descendants of Vikings who had settled there in the 10th century. In the 11th century, some of them – mainly as mercenaries – began arriving in southern Italy and Sicily, taking advantage of local conflicts among Byzantines, Arabs, the Papacy, and local rulers. Over time, under the leadership of the Hauteville family (notably Robert Guiscard and Roger II), they conquered Apulia, Calabria, Naples, and Sicily. In 1130, Roger II crowned himself King of Sicily, establishing a kingdom that encompassed much of southern Italy.

In the mid-12th century, Bari often rebelled against central Norman authority. In 1155, backed by the Byzantine Empire, the city rose up against William I, son of Roger II. In retaliation, the king ordered the destruction of the city walls and the castle – an act of repression and a demonstration of power against local dissent. Around a century later, following the takeover of the Kingdom of Sicily by the Hohenstaufen dynasty, the castle was rebuilt by Emperor Frederick II, son of Constance, daughter of Roger II. The reconstruction, carried out between 1233 and 1240, gave the castle its characteristic trapezoidal layout, with a central courtyard, massive corner towers, and a moat (except on the northern side, which bordered the sea).

In the 13th century, following the death of Frederick II and the fall of the Hohenstaufen dynasty, Bari came under the control of the Angevins, and from 1442, the Aragonese, as part of the Kingdom of Naples. During this period, the castle underwent gradual transformations – especially in the Renaissance era, when Isabella of Aragon and her daughter Bona Sforza transformed it into an elegant residence. A monumental staircase, chapel, and courtly interiors were added. In 1504, Bari fell under the rule of the Spanish Habsburgs. In 1696, a lightning strike hit one of the castle’s towers, igniting stored gunpowder and causing a major explosion that damaged both the castle and surrounding buildings.

After the War of the Spanish Succession, Bari came briefly under Austrian rule in 1707, and from 1734 became part of the Kingdom of the Two Sicilies, ruled by the Bourbon dynasty. During this time, the castle lost its residential status and was used as a prison and military barracks. In 1861, following the unification of Italy, Bari and its castle were incorporated into the newly formed Kingdom of Italy.

A popular legend is linked to the castle, involving Saint Francis of Assisi. During his journey to the Holy Land, he is said to have stopped in Bari, where Emperor Frederick II tested him by placing him in a tower with a young woman. Francis resisted the temptation, and the tower became known as the Monk’s Tower or Tower of Saint Francis.

Architecturally, the castle is defined by its massive stone structure, characteristic of medieval fortifications, designed to impress and defend. It is surrounded by a dry moat, once serving as an additional protective barrier, and accessed via a bridge that leads to the main gate. The layout follows a trapezoidal plan, with four sturdy corner towers framing a spacious central courtyard.

Yo can see the blend of architectural styles, reflecting the layers of history embedded in its walls. The robust Norman foundations are complemented by Swabian modifications combining military precision with elegant form. Gothic windows and arches soften a bit the austere structure, while later Renaissance additions give it a touch of refinement.

Exterior and interior views of the castle reveal the passage of time and a mix of architectural styles. The central courtyard feels rather bare, but it’s worth remembering this was originally a fortress, only later adapted during the Renaissance. The castle is largely unfurnished, with a few multimedia installations aiming to evoke its past

That said, much of the structure remains closed to the public due to ongoing restoration work. During my visit, I had the distinct impression that not everything has yet been unveiled — parts of the castle feel hidden or inaccessible, and some spaces could be better presented to help visitors connect with the site’s layered past. The inner courtyard, though spacious, felt somewhat stark and empty, offering little to linger over. With its few windows and fortress-like interiors, the castle clearly functioned more as a stronghold than a residence. Perhaps in the future, once renovations are complete, more of the building’s potential will be revealed.

Today, the Norman-Swabian Castle of Bari serves as a museum and cultural centre, hosting exhibitions, concerts, and artistic events. On the ground floor, visitors can explore collections of sculpture, ceramics, and archaeological finds – some original, others cast replicas. From an upper upper gallery at the ground floor, visitors can view archaeological excavations in the lower levels of the castle. The interior is sparsely furnished, with only a few pieces on display. However, visitors can walk through the chambers and along the defensive walls, where several rooms feature historical multimedia projections. The site also houses a Gipsoteca, a plaster cast museum displaying Romanesque art from Apulia, including details from the Basilica of Saint Nicholas in Bari and the Cathedral of Trani.

When I visited the castle in late 2023, one of the halls featured a visual narrative on the life of Queen Bona. Who was Bona? She was the granddaughter of Alfonso II of Aragon, King of Naples, through her mother, Isabella of Aragon. In 1518, after marrying King Sigismund I the Old of Poland, she was granted Bari and Rossano as a fiefdom by Emperor Charles V. Although she spent most of her life in Poland, the castle in Bari remained part of her hereditary estate. She managed her Italian holdings and played an active role in administering the castle and surrounding lands. Both Bona and her mother transformed the fortress into a Renaissance residence, adding a monumental staircase and chapel. During this period, the castle became the seat of a refined court blending Italian and Polish influences. Bona’s legacy in Bari is so profound that her sarcophagus was placed above the altar in the nearby Basilica of Saint Nicholas (Basilica di San Nicola).

The Norman-Swabian castle of Bari is not yet a fully curated museum space, but its structure, setting, and historical significance remain an integral part of the old town’s landscape.

Castel del Monte. Geometry, Mystery, and Silence

Despite its remote location, Castel del Monte attracts a steady flow of visitors – drawn not only by its UNESCO status, but also by its unique, almost mathematical design. Perched high on a hill and surrounded by quiet countryside, it feels detached from the everyday world, yet still manages to be surprisingly accessible.

Castel del Monte was commissioned by Holy Roman Emperor Frederick II (1194–1250), a member of the Hohenstaufen dynasty, who reigned as King of Sicily from 1198, King of Germany from 1212, and Holy Roman Emperor from 1220. The Apulia region fell under his direct rule as part of the Kingdom of Sicily, inherited from his mother, Constance of Sicily. It was constructed between 1240 and 1250.

Despite its fortress-like appearance and elevated position, Castel del Monte was not built for military purposes, as it lacks defensive features such as a moat or drawbridge. Its true function remains uncertain, with theories ranging from a hunting lodge or a place of study, to a symbolic expression of imperial power – or even an astronomical observatory.

Castel del Monte on approach

Castel del Monte stands in the Apulia region of south-eastern Italy, within the Alta Murgia National Park. It is located atop a hill 540 metres above sea level, around 20 kilometres from the town of Andria.

We reached Castel del Monte by car. Departing from Bari, the regional capital, we followed the A14 motorway towards Andria and continued along local roads. The drive took just over an hour. At the foot of the hill on which the castle stands, there is a small car park. Although conveniently situated, the parking area is quite limited and can become crowded in peak season. Fortunately, we had no difficulty finding a space, as we visited in mid-November on a misty, drizzling day. From the car park, the ascent to the hilltop is brief and can be done on foot.

Castel del Monte is a masterpiece of medieval architecture, renowned for its strict geometric precision and the harmonious blending of diverse stylistic elements. The core of the structure is a perfect octagon, with eight octagonal towers positioned at each corner. This motif repeats throughout: both floors feature eight rooms arranged around a central octagonal courtyard. Each outer wall is of equal length, and doorways and windows are placed in accordance with a strict axial rhythm, reinforcing the architectural coherence of the whole. The mathematical precision of the layout creates a strong sense of balance and symmetry.

The rooms themselves are architecturally restrained yet refined. The design draws on a mixture of stylistic influences, combining elements of Islamic, Romanesque, and Gothic architecture. Inside, Arab-style pointed arches contrast with classical Greco-Roman tympanums that crown several entrances, while Gothic windows, sculpted from pale limestone and white marble, introduce verticality. The central courtyard, open to the sky, serves both a practical and symbolic role – channelling light into the surrounding roomss while reinforcing the castle’s geometric core.

Today, the interior of Castel del Monte is entirely unfurnished. Visitors are invited to experience the architecture in its purest form – unmediated by decoration or modern reconstruction. The raw stone, the vaulted ceilings, and the spatial rhythm of the layout offer a contemplative, almost a monastic atmosphere.

Frederick II, who commissioned the castle was not only a powerful monarch but also a patron of knowledge. His court was a centre of intellectual exchange, bringing together the scientific, including mathematics and cosmology, and philosophical traditions of the Islamic world, medieval Christianity, and classical antiquity.

Frederick’s fascination with mathematics was reinforced by his association with leading thinkers such as Leonardo of Pisa – better known as Fibonacci. The renowned mathematician, who studied in North Africa, dedicated his Liber quadratorum to the emperor. Other scholars at Frederick’s court, such as Michael Scot and John of Palermo, translated key Arabic texts into Latin, enriching the emperor’s access to advanced ideas in geometry, astronomy, and numerical symbolism.

Although the identity of the architect is unknown, it is widely believed that Frederick himself played a significant role in the conceptualisation of the Castel del Monte. Central to the castle’s design is the number eight. In Christian tradition, the number symbolises regeneration and eternal life; in Islamic architecture, the octagon often mediates between the earthly square and the heavenly circle, reflecting a cosmological balance.

Since its construction in the 1240s, Castel del Monte has undergone several transformations. After Frederick’s death in 1250, it passed into the hands of successive dynasties ruling the Kingdom of Naples. Under Angevin and later Aragonese control, its symbolic imperial role diminished. Over time, it was repurposed – as a hunting lodge, a prison, and a military outpost.

By the 16th and 17th centuries, the castle had fallen into disrepair. Neglected and looted, its fine materials – including columns, marble cladding, and decorative details – were removed or sold. During this period, it also passed into private ownership.

Recognising its cultural significance, the newly unified Italian state acquired the castle in 1876 for 25,000 lire. Restoration work began in 1928 and continued in phases throughout the 20th century. In the 1950s, under the direction of Bruno Malajoli, further interventions helped stabilise the structure and restore elements of its integrity.

In 1996, Castel del Monte was inscribed as a UNESCO World Heritage Site. Today, it is managed by the Italian Ministry of Culture.

While the modern Italian word castello simply means “castle”, the name Castel del Monte uses the older, shortened form castel – and this is no coincidence. Castel is an archaic variant commonly used in the Middle Ages in proper names of places and fortifications. This linguistic form has been preserved in traditional place names such as Castel Gandolfo or Castel San Pietro.

Etymologically, the word derives from the Latin castellum, meaning “fortress” or “stronghold”. The abbreviated form was widely used in medieval geographic naming, much like San is used instead of Santo in the names of saints. Retaining this form in the name of the castle highlights its historical origin and connects it to the linguistic traditions of the time.

Castel del Monte may not overwhelm with grandeur or elaborate exhibitions, but its quiet presence lingers. There’s a sense of order in its geometry, uncertainty in its purpose, and stillness in its setting – a rare combination that makes the visit feel less like ticking off a landmark, and more like stepping into a space designed to make you pause. Geometry, mystery, and silence – it really is all there.

Suomenlinna. The Finland’s Historic Sea Fortress

About a year ago, we took a ferry trip from Tallinn, Estonia, to Helsinki, Finland. We had around 10 hours to explore Helsinki. Although it was a heatwave back home, the temperature in Helsinki was about 17 degrees Celsius. The weather was quite pleasant, so after a brief walk around the city, we decided to take a ferry to Suomenlinna. This was my first encounter with Finland. While I have a decent understanding of Central and Western European history, I realised that in seeking information about this place, I am essentially learning Finnish history from scratch.

Suomenlinna is a sea fortress located on several islands off the coast of Helsinki. Also known by its Swedish name, Sveaborg (meaning Swedish Fortress), it was constructed in the 18th century when Finland was part of the Kingdom of Sweden. The fortress aimed at securing the kingdom’s eastern borders against Russian expansion. Suomenlinna, covering around 80 hectares across six islands (Kustaanmiekka, Susisaari, Iso Mustasaari, Pikku Mustasaari, Länsi-Mustasaari, and Långören), was one of the largest defensive projects in Europe and the world at the time, influenced by French fortification techniques. Suomenlinna served as the main base for the Swedish fleet in the eastern Baltic, strategically positioned at the entrance to Helsinki, making it a critical point in Sweden’s defence.

In the early 19th century, Europe was engulfed in the Napoleonic Wars. Sweden, a traditional adversary of Russia, faced a difficult geopolitical situation. In 1807, Russia, allied with France, demanded that Sweden join the continental blockade against Britain. When Sweden refused, Russia invaded Finnish territories under Swedish control. The Russian forces swiftly advanced westward, and in March 1808, they began the siege of Suomenlinna, cutting off the fortress from the rest of Sweden by sea. Despite its strong defences, the fortress’s garrison of about 6,000 soldiers faced dwindling supplies and uncertainty about further support from Sweden.

Admiral Carl Olof Cronstedt, the commander of the fortress, was under immense pressure. Morale among the soldiers was low, and supplies were running out. Realising that a prolonged siege could lead to starvation and disaster, Cronstedt decided to negotiate with the Russians. The Russian forces were well-prepared to continue the siege but were also open to negotiations to avoid unnecessary bloodshed. After weeks of talks and growing pressure from his own officers, Cronstedt eventually decided to surrender the fortress. On 3 May 1808, after brief negotiations, a surrender agreement was signed. The terms were relatively lenient – the garrison was allowed to leave with honours, and the Russians took control of the fortress without major damage. The surrender of Suomenlinna was a significant blow to Sweden, effectively deciding the outcome of the war. It opened the way for further Russian expansion into Finland. After the surrender, Russia quickly took control of the rest of Finland. Finland was officially annexed to the Russian Empire as an autonomous Grand Duchy. Under Russian rule, the fortress was expanded and modernised. The Russians added new fortifications and storage facilities to meet modern defensive needs, incorporating new military architecture and technology into the existing Swedish structures. The fortress also served as a military base and a prison for political prisoners.

After Finland declared independence in December 1917, the country was deeply divided, leading to civil war between the Whites and the Reds, each with different visions for Finland’s future. The Whites were conservative republicans, mainly from the middle class, landowners, the bourgeoisie, and officers, supported by wealthier farmers and intellectuals. They sought to establish a strong, independent Finnish state based on national and republican values, while maintaining traditional social and economic structures. They received crucial support from Germany, including military equipment, advisors, and troops. The Reds were a socialist and leftist movement drawn from the working class, poorer farmers, and radical intellectuals. They represented those who experienced deep social inequality and sought radical reforms to create a more just society. They aimed to establish workers’ rule and a socialist economic system inspired by the Russian Revolution of 1917, advocating for the state takeover of property, broad workers’ rights, and political reforms.

Suomenlinna played a key role in these events. During the civil war, it was seized by the Whites and used as a military base and stronghold. After the Whites won the conflict in May 1918, Suomenlinna was turned into a prisoner-of-war camp, holding mainly Red soldiers and those suspected of supporting the socialist movement. The camp’s harsh conditions, overcrowding, lack of food, and medical supplies led to high mortality among the prisoners. A place once symbolising resistance and strength had become a site of suffering and tragedy.

During World War II, Suomenlinna again served a military role, acting as a base for Helsinki’s air defence and a command post. Its strategic location at the capital’s entrance made it a critical element in Finland’s defence against Soviet bombings.

Today, Suomenlinna is known for its diverse architecture, reflecting its long history and the influences of various powers. The fortress includes many bastions, defensive walls, forts, and historic buildings, such as warehouses, barracks, and workshops. It is not only a tourist attraction but also a residential area with about 800 inhabitants. The fortress hosts numerous cultural events, including concerts, exhibitions, and festivals. Besides its historical significance, Suomenlinna offers beautiful landscapes. The fortress is easily accessible from central Helsinki, with regular ferries departing from Kauppatori square. In summer, tourist cruises also offer the chance to admire the fortress from the sea.
