Prazský Hrad (Prague Castle)

Despite its monolithic presence, Prague Castle is not a single structure but a collection of structures dating from the 10th to the 20th century, all linked by internal courtyards. The most important are the cathedral, the Chrám svatého Víta, clearly visible soaring above the castle walls, and the Královský palác, the official residence of kings and presidents and still the center of political power in the Czech Republic.
