Doksy Castle, Cultural monument and château in Doksy, Czech Republic

Doksy Castle is a three-winged building arranged in a U shape, with outbuildings and a walled English park. Its western Renaissance wing has a decorated facade, the second wing with buttresses is early Baroque, and the third wing is dominated by a tower with an onion dome.

The castle's founding is uncertain: Rudolf Anděl dates it after 1553, when Saloména z Janovic inherited Doksy and built it with Mikuláš Zajíc z Hazmburka; Pavel Vlček credits Adam Berka z Dubé with the western wing, acquired in 1558. Václav Berka z Dubé added the second wing, and after 1622 it passed to Albrecht z Valdštejna. The Valdštejns held it until 1945.

Since December 2019 the castle has housed the town's tourist information centre, municipal library and the Čtyřlístek museum, named after the Czech comic series. Guided tours focus on the Valdštejn-Vartenberk family, who owned the estate until 1945.

The castle opened to the public in December 2019, when the tourist information centre, town library and Čtyřlístek museum moved in. The grounds and the 19th-century English park are also accessible, with a nature trail and information panels running through the park. The bus station is next to the grounds; the train station on line 080 is about 1.5 km away.

The castle grounds form a European Important Site (CZ0513659) protecting a colony of greater mouse-eared bats. The 0.56-hectare area, including the park, was listed for this bat population, so visitors may notice the site's conservation status alongside its buildings.
