Talmberk Castle, Castle ruin in Talmberk, Czech Republic

Talmberk Castle is a medieval castle ruin on a hill spur in the village of Talmberk, about three kilometres north of Rataje nad Sázavou. Its rectangular inner courtyard was flanked by a tower in the northeast, a residential building in the south and a bailey in the north, separated by a ditch. Only remnants of the ring wall and tower survive, partly built over by village houses.

The castle was first mentioned in 1297, when Vilem of Talmberk was named. In 1390 Havel Medek of Valdek seized it and imprisoned Diviš of Talmberk; a provincial court ruling forced him to release Diviš and return the castle in 1397. By 1533 it was recorded as deserted.

The name Talmberk derives from the Middle High German Tâhele, meaning jackdaw, so it means "Jackdaw Mountain"; records give Talmberg (1297), Talnberg (1312) and Thalmberk (1337). The village of Talmberk and nearby Úžice are settings of the video game Kingdom Come: Deliverance, which also uses Diviš of Talmberk and his story.

The ruin stands on a hill spur in the middle of Talmberk village, not in a valley; the ground falls steeply to the east, south and west. Most of the castle area lies on private plots, so visitors keep to the surviving ring wall and tower fragments. The site is freely accessible at any time.

The village of Talmberk and nearby Úžice appear as locations in the video game Kingdom Come: Deliverance, which also draws on Diviš of Talmberk and his story. The castle's name comes from the Middle High German Tâhele, meaning jackdaw, so Talmberk means "Jackdaw Mountain".
