Holoubek Castle, Castle ruin in the Třebíč District, Czech Republic

Holoubek Castle is a ruin on a hill that now forms the shore of the Dalešice Reservoir, about 1 km north of Chroustov. The site is surrounded by water on three sides, and its masonry remains stand above the waterline.

Holoubek was probably founded by the lords of Starče and is first mentioned in 1353, when Konrád Payer transferred it to his brother Bohuš ze Starče. His sons sold it in 1392 to Martin of Jemnice and Radotice; Jindřich Zajímač z Jevišovic seized it and used it for raids, and after a lawsuit Martin hired an army and conquered it in 1407. In 1440 the Velké Meziříčí assembly decided to demolish it, and by 1447 it was listed as deserted.

The castle's name Holoubek means "little dove" in Czech, and it was also called Taubenstein or Plešický hrad. Its owners, the lords of Starče and later Jindřich Zajímač z Jevišovic, used it as a base for plundering campaigns, which is why the Velké Meziříčí assembly had it demolished.

The ruins are easily accessible from the village of Plešice via a hiking trail with free entry to explore the site. Visit during warmer months when paths are dry and visibility is clearer for walking around the walls and foundations.
