Nové Mitrovice Castle in Přestavlky, Cultural monument in Přestavlky, Czech Republic.

Nové Mitrovice Castle, also called Přestavlky Castle, is a Baroque château built in 1736 on the site of an earlier fortress at the northern edge of Přestavlky. It is a two-storey building with a mansard roof, a U-shaped plan with a central risalit and side wings, and a facade richly decorated with stucco. A park with exotic trees surrounds it.

The Vratislav family of Mitrovice held the Přestavlky estate in 1670–1685 and again from 1724 to 1804. In 1736 Count Jan Josef had the castle built on the site of an earlier fortress. The Blaschke family owned it from 1867 until its expropriation after World War II, and since 1959 it has housed a school and later a children's home.

The castle's name recalls the Vratislav family of Mitrovice, who held the Přestavlky estate from 1670 to 1685 and again from 1724 to 1804; Count Jan Josef had it built in 1736. From 1867 to 1946 it belonged to the Blaschke family, expropriated after World War II. Since 1959 it has housed a children's home, so the building is not open to visitors.

The castle stands on the northern edge of Přestavlky, part of the Sedlec-Prčice municipality in the Příbram district. It is not open to the public: since 1959 it has housed a children's home, and the surrounding park with exotic trees is also closed. The building can therefore only be viewed from outside.

The castle stands on the site of an older fortress, replaced in 1736 under Count Jan Josef of the Vratislav family of Mitrovice, who held the Přestavlky estate from 1724 to 1804. The family had also owned it earlier, from 1670 to 1685.
