Peruc Castle, Rococo château in Peruc, Czech Republic.

Peruc Castle is a château in the market town of Peruc, Louny District, whose present form results from a Rococo remodelling carried out between 1760 and 1770 for the Ledebur family. The Baroque rebuilding was designed by Antonio della Porta and then led by Pietro Paolo Columbani, in two stages, the first finished in 1724. The grounds include the adjoining park and the nearby neo-Gothic Božena's spring.

A fortress founded at the start of the 14th century by Jetřich of Peruc passed to the Pětipeský family, and before 1597 it was rebuilt as a Renaissance château. Antonio della Porta and Pietro Paolo Columbani led a Baroque reconstruction completed in 1724, followed by a Rococo remodelling in 1760–1770 under the Ledeburs.

The castle's name is tied to the village of Peruc, whose forecourt fortress was founded around 1300 by Jetřich of Peruc. In the 19th century František Palacký visited his friend František Daneš here, and the writer Svatopluk Čech spent part of his childhood in the village; a memorial room to Čech opened in the so-called Blue Salon in 1965.

The south wing, where Emil Filla had his flat and studio from 1947 to 1952, is subject to a dispute between the regional Gallery of Benedikt Rejt and the private owner, so access is not guaranteed. The castle has been in private hands since 2007 and stood empty for years; check the current state before planning a visit.

The castle's heritage designation since 1964 covers not only the building but also the adjoining park and the nearby neo-Gothic Božena's Spring (Boženina studánka). The complex has been owned by the town of Peruc since 1989, which sold it in 2007; repair costs were then estimated at 130 million Czech korunas.
