The Basilica of Saint George and the Basilica of St. Vitus were founded under the reign of Vratislaus I, Duke of Bohemia and his son St. Wenceslas 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. A Romanesque palace was erected here during the 12th century.
