Our recent twelve-day journey took us through the Czech Republic, Bavaria and the Austrian Alps. As we travelled back and forth across the borders between the three countries, stopping in Salzburg felt like a natural part of the route. After days of changing weather, mountain roads and historic towns, we arrived there on one of the hottest days of the trip. The temperature climbed well above 30°C and the sky was almost cloudless

No matter where you walk in Salzburg’s historic centre, your eyes are naturally drawn to the massive walls of Hohensalzburg Fortress. Standing high on Festungsberg Hill, it has dominated the city’s skyline for almost a thousand years and remains one of Salzburg’s most recognisable landmarks. Visiting it felt like an obvious choice. Although we had only one day to explore Salzburg, we deliberately set aside a few hours for the fortress. We spent our time walking through its courtyards, along the defensive walls and between its viewpoints, taking in both the architecture and the spectacular views across the city and the surrounding Alps.

Salzburg

To understand Hohensalzburg Fortress, it is worth looking first at the history of Salzburg itself. Unlike many other European cities, Salzburg was not simply part of a kingdom or duchy. For centuries, it was the capital of the Prince-Archbishopric of Salzburg, an independent ecclesiastical state within the Holy Roman Empire. The Holy Roman Empire was a loose federation of hundreds of kingdoms, duchies, principalities and ecclesiastical states in Central Europe that existed from 962 to 1806 under the nominal authority of an elected emperor.

The rulers of Salzburg were Prince-Archbishops. They were not only senior church leaders but also secular rulers who governed their own territory, collected taxes, administered justice and maintained an army. In other words, they exercised both religious and political power, making Salzburg one of the most influential ecclesiastical states in Central Europe.

The city’s prosperity was built largely on the salt trade, from which Salzburg takes its name. Salt was one of medieval Europe’s most valuable commodities, bringing wealth that allowed the Prince-Archbishops to finance churches, monasteries, public buildings and ambitious construction projects. It also gave them the means to build and continuously strengthen the fortress overlooking their capital.

By the beginning of the nineteenth century, however, the political landscape of Europe was changing rapidly. The French Revolution and the rise of Napoleon Bonaparte triggered a series of wars that transformed the map of the continent. One of the consequences was the gradual dissolution of the Holy Roman Empire, whose hundreds of kingdoms, duchies, free cities and ecclesiastical states had existed for centuries under the nominal authority of an elected emperor. Salzburg, despite its long tradition of independence, could not escape these changes.

In 1803, the Holy Roman Empire underwent its final major constitutional reorganisation, which secularised the Prince-Archbishopric of Salzburg. It became the Electorate of Salzburg and was granted to Ferdinand III of Habsburg, who had lost the Grand Duchy of Tuscany to Napoleon’s reorganisation of Italy. Although the city remained prosperous, its unique political status had come to an end.

The Napoleonic Wars brought further upheaval. After Austria’s defeat at the Battle of Austerlitz in 1805, Salzburg was incorporated into the Austrian Empire under the Treaty of Pressburg, only to change hands again a few years later. Following another Austrian defeat at the Battle of Wagram in 1809, Napoleon transferred most of Salzburg to the Kingdom of Bavaria, one of France’s closest allies. After Napoleon’s final defeat, the Congress of Vienna redrew Europe’s borders once more, and in 1816 Salzburg became a permanent part of the Austrian Empire, bringing to an end one of the most remarkable chapters in the city’s history.

The Fortress

The history of Hohensalzburg Fortress began in 1077, when Archbishop Gebhard von Helfenstein ordered the construction of the first fortifications on Festungsberg Hill. Europe was then in the midst of the Investiture Controversy, a political and religious conflict between Pope Gregory VII and Holy Roman Emperor Henry IV over the right to appoint bishops. As one of the Pope’s supporters, Gebhard needed a secure stronghold that could protect both himself and the authority of the Archbishopric of Salzburg.

The original fortress was far smaller than the impressive complex visitors see today. Built mainly of timber and stone, it served as a defensive refuge rather than a permanent residence. Over the following centuries, however, every generation of Prince-Archbishops expanded and strengthened the fortress, adapting it to new military technologies and changing political circumstances.

The transformation that shaped much of today’s Hohensalzburg Fortress took place at the end of the fifteenth century under Prince-Archbishop Leonhard von Keutschach. During his long reign, the medieval fortress was extensively enlarged, new defensive walls and towers were added, and many of the buildings that still define its appearance today were constructed. If you notice a turnip carved into stonework or decorating gateways during your visit, it is not a random ornament but the personal heraldic emblem of Leonhard von Keutschach.

One of the most remarkable facts about Hohensalzburg Fortress is that it was never captured by force during its long history. For more than nine centuries, despite wars, political upheavals and changing military technology, no enemy army succeeded in taking the fortress by assault. Its strength lay not only in its massive defensive walls but also in its location. Rising high above Salzburg on Festungsberg Hill, the fortress offered commanding views of the surrounding valleys and the approaches to the city. Any attacking force would have faced a difficult uphill advance while remaining fully exposed to defenders positioned on the walls and towers above. Although Hohensalzburg was strengthened repeatedly to keep pace with advances in siege warfare, it was rarely tested in large-scale military confrontations.

The fortress remained in military use until the beginning of the nineteenth century. During the Napoleonic Wars Salzburg was occupied by French forces. Unlike many medieval fortresses that ended their history in spectacular sieges, Hohensalzburg’s final military chapter was remarkably uneventful. In December 1800, during the War of the Second Coalition, French troops advanced into Salzburg after Austria suffered a series of defeats. Recognising that further resistance was pointless, the military commander surrendered the fortress without a major siege or prolonged fighting. After more than seven centuries of defending the city, Hohensalzburg passed into French hands almost peacefully.

During the nineteenth century Hohensalzburg was adapted to new purposes rather than abandoned. Parts of the complex were used as military barracks and storage facilities, while some sections served as a prison. The Austrian army carried out maintenance and limited alterations that helped preserve the buildings rather than fundamentally changing them. Unlike many European castles that fell into ruin or were dismantled for building materials, Hohensalzburg remained in continuous use.

By the late nineteenth and early twentieth centuries, attitudes towards historic monuments had begun to change. Restoration work focused on preserving the medieval and Renaissance fabric of the fortress, while improved access – including the opening of the Festungsbahn funicular in 1892 – made the site increasingly accessible to visitors. Today Hohensalzburg is one of Austria’s best-preserved medieval fortresses and one of the country’s most visited historic monuments.

Exploring the Fortress

We reached Hohensalzburg Fortress by the historic Festungsbahn funicular. Within a few minutes, the streets of Salzburg were left behind and replaced by stone walls, gateways and panoramic terraces overlooking the city. After leaving the funicular, we found ourselves on one of the lower viewing levels before realising that a lift continued to one of the highest accessible parts of the fortress. Starting our visit there turned out to be a good decision. Instead of working our way upwards, we could gradually explore the complex while making our way back down through its courtyards, passages and defensive walls.

One of the things I enjoyed most was that Hohensalzburg never felt like a place with only one route or one main attraction. There is a suggested direction for visitors, but it is easy to wander at your own pace, choosing different staircases, gateways and terraces as you go. Some areas are lively with visitors stopping to admire the views, while others are surprisingly quiet, making it easy to imagine what the fortress must have felt like centuries ago. In many ways, the experience reminded me of walking through Mont Saint-Michel, Stirling Castle or Suomenlinna. Not because they look alike, but because they invite you to explore rather than simply move from one exhibition to the next. Every turn reveals another section of wall, another courtyard or another viewpoint, and the pleasure comes from discovering the fortress little by little instead of following a fixed itinerary.

We spent around two hours exploring the fortress grounds, which felt like just the right amount of time. Although we did not visit the historic state rooms during this visit, exploring the fortress walls, courtyards and defensive structures gave us a clear understanding of how the fortress functioned and why it occupied such a strategic position. For us, the real attraction was the fortress itself – its scale, its medieval architecture and the freedom to simply walk, look around and enjoy the remarkable setting above Salzburg.

One of the greatest rewards of visiting Hohensalzburg Fortress is the view. From the defensive walls and viewing terraces, almost the entire Old Town of Salzburg unfolds below, with its narrow streets, church towers and distinctive rooftops.

Looking down from the fortress, it becomes easy to understand why this hill was chosen almost a thousand years ago. The position offered an uninterrupted view of the city and the surrounding valleys, allowing the Prince-Archbishops to watch over both their capital and the routes leading towards it. The fortress was not simply built above Salzburg – it was built to dominate it.

The panorama stretches far beyond the city itself. On a clear day, the surrounding mountains form a spectacular backdrop, reminding visitors that Salzburg lies on the northern edge of the Alps. Even after spending hours exploring the walls and courtyards, it is worth taking a moment to simply stand still and enjoy the scenery. It is one of those views that encourages you to slow down and appreciate both the landscape and the history that shaped it.

If you are planning a visit to Salzburg, I would certainly recommend setting aside a few hours for Hohensalzburg Fortress. It is not only one of the largest and best-preserved medieval fortresses in Europe but also one of those places where history, architecture and landscape come together in a way that is both easy to understand and genuinely enjoyable to experience.
