The fortress's history
The first defences on Fortress Hill at Kłodzko existed as early as the Middle Ages — a wooden stronghold, later a stone castle of the Bohemian dukes (the County of Kłodzko). In the 16th and 17th centuries the Habsburg rulers of Bohemia extended the castle into a Renaissance fortification. The turning point came with the Silesian wars of the 18th century — in 1742 Prussia took Silesia and the County of Kłodzko from the Habsburgs.
In the middle of the 18th century the Prussian king Frederick the Great ordered the fortress rebuilt as a modern bastion fortress on French models (Vauban). That is when the present layout took shape: a system of bastions, ravelins and forts around a central keep. The fortress was to guard against any Austrian return. In fact it was never taken by storm — only once, in 1807, did it surrender to Napoleon after a long siege.
After the First World War the fortress lost its military importance. In the Second it served as a prisoner-of-war camp, and the tunnels as an armaments factory. After the war, when Kłodzko passed to Poland, it was a store for a time and then gradually opened to visitors. Today it is run by the Museum of the Kłodzko Land.
What you see
- The Great Bastion and the Little Bastion — massive earth-and-stone defensive corners you can climb
- The keep — the central watchtower with the best panorama
- The underground tunnels and casemates — kilometres of passages in the rock, seen with a guide
- The main gate and guardhouse — a beautiful piece of Baroque architectural detail
- The fortress well — about 80 m deep, essential in case of siege
- The museum displays — the history of the fortress, weapons, uniforms and models of sieges
- The moat — once flooded, today dry and walkable
The visitor routes
There are two routes. The surface route (about 1.5 hours) leads along the walls, bastions and courtyard — you can go round on your own with a map. The underground route (about 45 min) is guided only, in groups, with departures every 30–60 minutes in season. The tunnels are low in places (1.7 m), narrow and poorly lit — not for anyone claustrophobic.
Tickets: a combined ticket (both routes) about 30 zł for adults and about 20 zł for children and students, with seasonal variations. Open all year, daily 9:00–18:00 in season and for shorter hours out of it. The best months: May and September (few people), and in summer the early morning before the coach parties arrive.
Worth knowing
- Warm clothes — the underground tunnels stay at about 10–12°C all year
- Footwear — comfortable; there are steps and uneven surfaces
- Time needed — a full 2–3 hours for both routes
- Accessibility — the surface route partly suits those with limited mobility, the underground route does not
- From Kłodzko market square — 10–15 minutes uphill on foot (or a short drive to the fortress car park)
- Restaurant — within the fortress complex, with regional and old Polish cooking
