Tmaň Castle, Cultural monument in Tmaň, Czech Republic

Tmaň Castle is a one-storey château with four wings around a rectangular courtyard, in the village of Tmaň south of Králův Dvůr. A tower rises one storey above the south entrance wing, and the north wing incorporates masonry of the earlier Gothic fortress. The ground floor retains a late Gothic rectangular portal and ridge vaults.

A fortress at Tmaň is first documented in 1540, when Oldřich Karel of Svárov transferred it with the village and Málkov to his uncles. Vilém Jaroslav Greifenfels of Pilsenburk had the old fortress rebuilt as a Renaissance château; the only major later change was a Baroque roof, probably ordered by Count Bedřich Desfours, owner from 1755 to 1802. The Noltsch family held it until 1945.

The village's name, Tmaň, is linked to the noble Tmaň family, whose members Albert and Markvart are recorded in the 14th century; Jan Koberec of Tmaň served as huntsman at the court of King Wenceslaus IV. The castle later passed through the Trmal of Toušice family, and Zdeněk Trmal took part in the Bohemian Estates uprising, dying near Sedlčany in 1619.

The château is now a private seniors' home run by Senlife, opened in June 2024 after reconstruction begun in 2022, so the interiors are not open to visitors. The four wings enclose a rectangular courtyard; the entrance tower rises one storey above the south wing. The adjoining park was partly damaged by a playground and utility buildings.

A black knight chess piece sculpture created by Vladimír Glaser in 2011 stands near the castle grounds. This unexpected artistic addition links history and contemporary art in a surprising way.
