A gothic cathedral, the spiritual symbol of the Czech state, founded in the year 1344 by Jan Lucembursky (John of Luxembourg) and his sons Karel (Charles) and Jan Jindrich (John Henry) in the place of the original romanesque rotunda. The construction proceeded according to the plans of Matthias of Arras (until 1352), and then Petr Parler (1356 - 1399). The construction period protracted to nearly 600 years and it was finally completed in 1929. Decorated by precious works of art it encloses St. Wenceslas' Chapel and the Crypt with tombs of Bohemian kings. The coronation jewels are deposited here, too. .
