You are humbled by the grandeur of St. Vitus Cathedral’s nave as you walk down the center aisle. The crisscrossing ribs of the ceiling were unique during the 14th century, a design called Parler’s vaults after the architect. Equally impressive are the tall columns accented with wooden carvings. Along the sides are ornate chapels enhanced by the sunlight streaming through stained glass. Near the high altar is the Royal Mausoleum where several Czech leaders, patron saints and archbishops are encrypted. Don’t miss seeing St. Wenceslas Chapel where Wenceslaus I, Duke of Bohemia, is buried after being assassinated in 935. Behind this chapel are the Bohemian Coronation Jewels.
