The exterior is towering, the interior is magnificent, the space is magnificent, and the people are extraordinarily small in the church. Walking around the church, everything is shocking, slender columns, straight lines, pointed rib vaults, symmetrical layout, giving a strong sense of visual impact, this kind of high, straight, pointed and strong upwards The styling style characterized by the momentum is a reflection of its powerful and vigorous vitality, and it also creates a feeling of approaching God and heaven. The imperial mausoleum is located in front of the altar of the nave, and preserves the emperor's plaque in the basement of the cathedral, famous for the tombs of St. Wenceslas, Charles IV and Ferdinand I. Visit: The stained glass windows of the 20th century, the mausoleum of the emperor, and the tomb of Jean Neboms. Colorful stained glass windows are the wonderful pens of the church. When the sun comes in, the colorful light and shadow are reflected through the window wall. Most of the characters on the glass come from the Bible, nothing more than the crucifixion of Jesus, the Three Dynasty The Holy, the Annunciation, the Last Supper, and the twelve disciples of Jesus Christ, the saints in the church, and the Old Testament Old Testament are so beautiful that they can make illiterate believers understand Christian doctrine. The most striking of these is the mosaic of the 40,000 mosaics on the top of the church, the "final trial" and the stained glass window of the famous Czech painter Mucha, "The Window of Mucha".
