The Undergrounds at Ksiaz Castle

Ksiaz Castle is a huge structure located within the administrative city limits of Walbrzych. In Silesia, in terms of size, is second to none. After many modifications, the castle today is a mixture of different architectural styles, from Gothic to the history-forming early 20th century architecture.


Since 1509, the building has been owned by the Hoberg family, known later as the Hochberg family. Ksiaz Castle, along with its vast estates, remained in the hands of Hochberg family until World War II, when it was confiscated by the Nazis. In 1939 the Nazi state took, on the pretext of alleged treason, as a result of their English connections, most of the estates belonging to the Hochberg family. In 1941, the Nazis finally took over the castle and began its reconstruction, by command of the Fuehrer. At the same time, under the building, several thousand prisoners were digging a tunnel network which was in the framework of the “Riese” Project, which also was the reason for the mineshafts being dug in the Owl Mountains. However, before the work was completed, Germany was forced to surrender. Part of the underground section of the complex at Ksiaz Castle are two hollow excavated chambers, located 15m and 50m below the main courtyard. The first chamber, that is open to the public, is fully concreted and has a total length of about 90m at the level of the Goddess Flora Terrace and the adjoining terrace. It connects the castle directly with the terraces and the main shaft. It has a guarded sentry post, and exit on the Horseshoe Terrace and is connected to one of the castle lifts, which allows communication with all the floors of the castle, as well as the nearly circular staircase in cross-section, to ensure communication with the ground floor of the castle.
The second excavated chamber is much more extensive, has been used for mounting super-sensitive measuring instrumentation of the Geophysical Observatory of the Polish Academy of Sciences.
The Ksiaz Castle and Palace Complex is a historic building, which is listed as a historic monument as part of the Ksiaz Landscape Park.
