Castle Horka, Baroque château in Horka II, Czech Republic

Horka is a one-storey baroque château with seven window axes, built in 1765–1770 on the site of an older fortress. Its main façade has a central risalit with a balcony and a tympanon, and the family coat of arms of Josef Štangler, who bought the estate in 1845, is above the entrance. A chapel of St Joseph with rococo wall paintings was added to the east side in 1769.

Horka began as a fortress built by Oldřich Malovec in the second half of the 16th century; it was first mentioned in 1578. After 1642 it lost its residential role, but in 1748 it again became the seat of a small estate. In 1765–1770 Jan Adolf of Trauttmansdorff had the old fortress rebuilt as a baroque château with a Chapel of St Joseph. The Štangler family owned it until 1949.

The château's name recalls the village of Sloupná, bought in 1553 by Pavel Malovec; his son Oldřich built the fortress first mentioned in 1578. For over a century it was called Horka nad Sloupnou. The Chapel of St Joseph, added in 1769, has Rococo fittings and wall paintings, with a framed main altar to St Joseph and a side altar to St John of Nepomuk.

The château stands in Horka II southeast of Zruč nad Sázavou, in the Kutná Hora district. It now houses the municipal office, so the building is best seen from the adjacent farmyard, whose gate and walls are also protected; the farm buildings themselves are in poor condition.

The chapel of St Joseph was added to the east side in 1769, during the baroque rebuilding, and has a rococo interior with wall paintings, a framed main altar of St Joseph and a side altar of St John Nepomuk. The family coat of arms of Josef Štangler, owner from 1845, sits above the main entrance.
