Zámek Týn nad Vltavou, Baroque château in Týn nad Vltavou, Czech Republic

Zámek Týn nad Vltavou is a two-storey Baroque building with later Neoclassical elements, standing on the northern slope of Míru Square on the site of three older houses. Its mansard roof dates from after the 1796 fire. The ground floor has vaulted ceilings, the upper floors flat ones, and a two-armed staircase survives inside; the town museum occupies the building.

The château was built in 1698–1699 for the Prague Archbishopric's estate administration, replacing the ruined castle destroyed in the Thirty Years' War. Archbishop Jan Josef Breuner ordered it on the site of three older houses, including that of governor Matyáš Arnošt Kherner, confiscated after his death in 1661. Architect Antonio de Allfieri designed it; a 1796 fire led to classicist alterations.

The château houses the town museum, whose displays cover the history of the Vltavotýn region and its figures, among them the theatre director Alfréd Radok. A separate exhibition is devoted to moldavites, the green South Bohemian gemstones, and the second floor holds a large display on puppetry.

The château stands on the northern slope of Míru Square in the historic core of Týn nad Vltavou. The town information centre behind the building arranges entry to the historic underground passages cut into the rock beneath it. The municipal museum and its exhibitions occupy the château itself.

The cellars under the château connect to extensive underground passages cut directly into the rock. The town information centre behind the building controls access to this historic underground, so the passages are entered from the rear of the château rather than from the museum rooms.
