Pražský hrad (Prague Castle) is a castle in Prague where the Czech kings, Holy Roman Emperors and presidents of Czechoslovakia and the Czech Republic have had their offices. The Czech Crown jewels are kept here.
The history of the castle stretches back to the 9th century (870). The first walled building was the church of Our Lady. The Basilica of Saint George and the Basilica of St. Vitus were founded in the first half of the 10th century. The first convent in Bohemia was founded in the castle, next to the church of St. George. In the 14th century, under the reign of Charles IV the royal palace was rebuilt in Gothic style and the castle fortifications were strengthened.
