Książ Castle

Książ Castle is a large multi-wing castle complex near Wałbrzych in Lower Silesia, Poland, occupying a sandstone ridge above the Pełcznica valley. The complex combines medieval origins with later Baroque and Rococo rebuilding and contains several hundred rooms in its main palace block.

Visitors explore state rooms, historic interiors, and extensive terraces and gardens that slope down toward the surrounding parkland; guided tours cover principal halls and viewpoints. An extensive system of corridors and galleries beneath and around the castle, enlarged during the Second World War, forms a notable subterranean feature.

The site originated in the 13th century and was developed over centuries by regional noble families, most notably the Hochberg family, who transformed the complex into a palatial seat. In the 20th century, the castle was seized and modified during the Nazi period, leaving a legacy of underground works and later post-war restoration efforts.

Książ Castle sits above the town of Wałbrzych in Lower Silesia, in south-western Poland, surrounded by mixed forest and parkland and close to other Silesian historic sites.

• Scale and interiors: One of Poland's largest castles with roughly 400 rooms and a long history of changes in style from medieval fortification to palatial residence.
• Wartime tunnels: Subterranean wartime tunnels associated with Nazi Project Riese are beneath the castle; parts of these passages are now a visitor feature but remain restricted in sections.
