Třeboňský zámek, Renaissance castle in Třeboň, Czech Republic.

Třeboňský zámek is a Renaissance castle in the center of Třeboň, in the Czech Republic. Below the building runs an underground network of casemates connecting different sections, including the historical stables and a room once used as a dog kitchen.

The castle was founded in 1366 by the Rosenberg family and changed hands and form over many generations. After a serious fire in 1562, Vilém of Rosenberg had the building thoroughly rebuilt in the Renaissance style.

The gate from Masaryk Square bears the name Petrus Woko Ursini Gubernator and the date 1607, marking the Rosenberg builder. In the outer courtyard stands a 1712 fountain by Paul Ignaz Bayer with a raven pecking a Turk, recalling Adolf Schwarzenberg's victory at Raab. The castle also holds the Schwarzenberg archive, moved here from Kornhaus in the 20th century.

The castle sits right in the center of Třeboň and is easy to reach on foot from the main square. Guided tours run throughout the year and cover different parts of the building, from the private apartments to the underground passages.

The Schwarzenbergs kept the castle until 1940, when the Gestapo seized it; after the war it passed to national administration and was nationalised in 1947. In summer the family rented the complex out as a hotel, and the prince arrived by train at Třeboň-Lázně station, where a carriage waited for him.
