Diana (German: Dianaberg) is an almost abandoned settlement located in the forests south-east of Rozvadov municipality, Tachov District, Czech Republic. The population is around 30 people. The area of Diana, today a part of Rozvadov, consists also of a former glasshouse and a large defunct woodworking factory. A hunting mansion Diana (first mentioned in 1742) is situated in the settlement. The mansion, which was in the past owned by the Kolowrat noble family, was named after the goddess of hunting. Its project is sometimes attributed to the Czech-Italian architect Jan Santini Aichel.
