Třešť Castle, Renaissance Revival château in Třešť, Czech Republic.

Třešť Castle is a four-wing, two-storey building with an inner courtyard and four corner towers, one on each side. The west portal is by Mořic Grimm, Baroque soldier statues stand at the entrance, and the west facade has a clock tower with an onion dome.

A fortress on the site was first recorded in 1513, built under Václav Vencelík. In the second half of the 16th century Kryštof Vencelík had it rebuilt as a Renaissance castle by the Italian builder M. Grimm, with arcades and sgraffito in the inner courtyard. Baroque alterations followed in 1714, and in 1860 the Sternbach family gave it its present Neo-Renaissance form.

The Vencelík family held Třešť for 130 years until 1626, when their estates were confiscated after the Bohemian Revolt; Zikmund Matěj Vencelík took part in the uprising of 1618–1620. The castle later passed to the Herbersteins, the Gayers of Edelbach and from 1844 to the Tyrolean Wenzel-Sternbach family.

The castle functions as a hotel with 57 renovated rooms and modern facilities for conferences and events. A wellness center on site provides additional amenities for guests seeking relaxation.

A Renaissance-era footbridge once linked the castle to the nearby Church of St Martin; it has not survived. The west facade carries a clock tower with an onion dome, and Baroque statues of soldiers stand by the entrance portal, whose author was Mořic Grimm.
