Castle Diana, Cultural monument château in Diana, Czech Republic.

Castle Diana is a four-winged, two-storey building with a cross-shaped plan, its centre rising into a hexagonal tower topped by a dome. Smaller buildings linked by masonry bridges connect to further pavilions. The protected complex also includes an administrative building (No. 10), an obelisk and a landscape park.

The château was founded in the first half of the 18th century by the Novohrad branch of the Kolowrat family, probably František Zdeněk and František Václav Novohradský z Kolovrat. It was built as a hunting lodge, hence the name after Diana, the Roman goddess of hunting. The first written mention dates from 1742. The family held it until nationalization in 1948, with a two-year break during World War II.

The castle is named after Diana, the Roman goddess of hunting, because it was founded as a hunting lodge. A game park and an English landscape park once adjoined it. After 1992 the Kolowrat family regained the building, and Dominika Kolowrat-Krakowská began its gradual reconstruction.

The castle is currently undergoing restoration work focused on preserving its historical features. Visitors should be aware that access and viewing opportunities may be limited due to ongoing construction.

The castle's name refers to Diana, the Roman goddess of hunting, because it was founded as a hunting lodge. A game park and an English landscape park were attached to it. The grounds also hold an obelisk and a separate administrative building (No. 10).
