Pětipsy Castle, Ruin of a castle in Pětipsy, Czech Republic

Pětipsy Castle is a ruin of a Gothic fortress rebuilt into a château in Pětipsy, about nine kilometres southeast of Kadaň. The three-storey Gothic core has walls 1.8 m thick; Renaissance and Baroque wings enclose a courtyard, and only perimeter walls and some vaulted ground-floor ceilings survive.

A first mention of Pětipsy dates from 1226, when the village belonged to Doksany Abbey. Around 1322 Fridrich of Egerberk built a water fortress here, held by his family for nearly 200 years; in 1404–1407 Odolen the Younger Pětipeský imprisoned his neighbour Vlada of Poláky in it. The Hrobčický family rebuilt it as a Renaissance château around 1560, and from 1630 the Thun-Hohensteins owned it until the 1923 land reform.

The castle's name comes from the village of Pětipsy, first recorded in 1226 as property of Doksany Monastery. The exhibition opened on 3 August 2024 is devoted to the Hodek family, who rented the farmyard from the Thuns and later bought it, and to Fridrich Pětipeský, founder of the fortress.

The castle has been regularly open to visitors since 3 August 2024, following a reconstruction of half the building that cost forty million crowns. The exhibition covers the Hodek family and Fridrich Pětipeský, founder of the fortress. The site lies about nine kilometres south-east of Kadaň.

The three-storey Gothic tower had walls 1.8 metres thick, and during the Renaissance rebuild it was enclosed within the new U-shaped château, which was surrounded by a moat. The entrance to the tower core was from the south.
