Kněžice Castle, Art Nouveau château in Petrovice u Sušice, Czech Republic.

Kneżice Castle is a château with Art Nouveau architectural features in Petrovice u Sušice, Czech Republic. Its design incorporates ornamental details and natural motifs typical of the Art Nouveau style throughout the building.

Kněžice village belonged to the Velhartice estate from the Middle Ages. A fortress was founded there in the 1590s and rebuilt in the first half of the 18th century as a Baroque château with a hipped roof. In 1906 the Silesian architect Leopold Bauer drew up plans, commissioned by Oskar Heintschel von Heinegg, for major alterations to the château and its farm buildings.

The castle was used as a retirement home from 1955 to 2002, then sold in 2003 to a foreign company that converted it into a restaurant and hotel opened in 2004. Episodes 6 and 7 of the second series of the TV show Ano, šéfe! were filmed here; the hotel closed a year later and the building was offered for sale.

The château stands in the northern part of Kněžice, a village that is part of Petrovice u Sušice. The memorial Kněžice maple grows in the park garden north of the building. The house has been in private hands since 2003 and served as a hotel and restaurant until it closed a year after filming.
