The Horažďovice chateau stands in the town of the same name above the Otava river.
A small, but strategically important, water fortress stood originally in the place of the present chateau. Through time it took the role of the Prácheň castle and it was enlarged into the Gothic town castle. The castle was property of the Lords of Strakonice in the 14th century, then the Lords of Hradec kept it and at the end of the 15th century brothers Jan and Racek of Kocov were owners of the castle. They often broke law and that was the reason, why the Emperor plundered the castle and the town. At the end of the 16th century the castle was under the ownership of the Švamberks, who rebuilt it into a Renaissance chateau. They reconstructed it one more time in the Baroque style in the 17th century and then the chateau became a possession of the Mansfeld family.
The four-winged building encloses the spacious courtyard. A town museum is located in the south-western part, which was built under the project of the Italian architect Salomini. Its main part is the hall with rich decoration. A small tower is situated in the north-western corner. A chapel, which was rebuilt into the Baroque style, with the preserved original early Gothic castle tower from the 13th century is a part of the chateau as well.
In the chateau there is a museum with exhibitions of the history of the town and its surroundings.
