The Metropolitan Cathedral of Saints Vitus, Wenceslaus and Adalbert is a Roman Catholic metropolitan cathedral in Prague, the seat of the Archbishop of Prague. Until 1997, the cathedral was dedicated only to Saint Vitus, and is still commonly named only as St. Vitus Cathedral.
This cathedral is a prominent example of Gothic architecture, and is the largest and most important church in the country. Located within Prague Castle and containing the tombs of many Bohemian kings and Holy Roman Emperors, the cathedral is under the ownership of the Czech government as part of the Prague Castle complex. Cathedral dimensions are 124 by 60 metres, the main tower is 102.8 metres high, front towers 82 metres, arch height 33.2 metres.
The current cathedral is the third of a series of religious buildings at the site, all dedicated to St. Vitus. The first church was an early Romanesque rotunda founded by Wenceslaus I, Duke of Bohemia in 930. This patron saint was chosen because Wenceslaus had acquired a holy relic – the arm of St. Vitus – from Emperor Henry I.
The Cathedral of St. Vitus had a tremendous influence on the development of Late Gothic style characteristic for Central Europe. Members of Parler workshop, and indeed, the Parler family (both of which were established at the building site of St. Vitus) designed numerous churches and buildings across Central Europe. More notable examples include Stephansdom cathedral in Vienna, Strasbourg Cathedral, Church of St. Marko in Zagreb and the Church of St. Barbara in Kutna Hora, also in Czech Republic. Regional Gothic styles of Slovenia, northern Croatia, Austria, Czech Republic, and southern Germany were all heavily influenced by Parler design.
