The Troja Castle (Troja Chateau) is a Baroque building in the Troja district of Prague located in the immediate vicinity of the Prague Zoo on the right bank of the Vltava River.
The castle should be called a villa. It is an echo of the splendid Roman suburban villas that its builder Václav Vojtěch Count of Sternberk saw on his travels. He started the construction in 1679, as his summer residence and also to obtain a title of nobility. He stayed here with his wife Klara and daughter.
