Rožmberk (German: Rosenberg) is a castle situated in South Bohemia near Rožmberk nad Vltavou in the Czech Republic. Considered one of the oldest castles in Bohemia, it stands on a promontory carved out on three sides by the river Vltava. It was first mentioned in 1253 in a document signed by Vok "von Rosenberg". It is regarded as the cradle of the House of Rožmberk, also known as the "Lords of the Rose", a historical Czech aristocratic family.
