Saint Vita Cathedral (Katedrala sv. Vita) is the most important landmark of Prague Castle. Apart from its rich architectural features, it is also the place where the royal family of Prague Castle is crowned and sleeps after its death. St. Vita Cathedral has undergone three extensions. The St. Winceras Round Cathedral in 929 AD was expanded into a rectangular Cathedral in 1060 AD. Charles IV in 1344 AD ordered the construction of the current Gothic architecture, but it was not completed until 1929 AD. Several visits to St. Vita Cathedral focused on stained glass windows in the 20th century, St. John's Tomb and St. Winceras Chapel. Walking into the entrance of the church, the colored glass on the left is the work of the famous Prague painter Moha, which adds a lot of modernity to this millennium-old church. Around the rear of the altar, the tomb of St. John is made of sterling silver and ornately decorated. He was an anti-religious reformer in 1736, so he was buried in the Cathedral of St. Vita and commemorated with the magnificent decoration of sterling silver. Continuing forward is the St. Winceras Chapel. Compared with the Sterling Silver Tomb of St. John in front, St. Winceras Chapel shows a brilliant golden glory. From murals to the minaret, it has golden decorations, which are of great artistic value. From the exterior, the Gothic Cathedral of St. Vita has many classical architectural features, such as arch pillars and flying buttresses on the gate, which are quite ornate. The old palace (Stary Kralovsky Palac) was the residence of the former King of Bohemia, and successive incumbents renovated different parts. The whole palace building is roughly divided into three floors. The entrance is the elevated Villa Dislav Hall, which is also the center of the palace. There are many images of early secretaries in the new territory Hall of the upper level. The lower level is the Gothic Charles IV Palace and the imitation Roman Palace hall. Most of the rooms were destroyed in the fire of 1541 A.D., so part of them are the relics of later reconstruction. Trace. St. George's Church is the red church with two towers behind St. George's Cathedral (Bazilika sv. Jiri). St. George's Cathedral is the best preserved Roman-style building in Czech Republic. It has been built many times since its completion in 920. The most recent one is at the end of the 19th century and the beginning of the 20th century. The cornerstone and two minarets of the church have been preserved since the 10th century. Saint George's Monastery is the first monastery in Bohemia. It was demolished in the 18th century and rebuilt as a military camp. Today it is the National Gallery. It collects Czech art works from the 14th to 17th centuries, including Gothic art, Renaissance and Baroque paintings of different periods. The Prasna Vez-Mihulka here, like the Prasna Vez-Mihulka in the Old City Square, was originally used as a fortress for guarding the city, but later for storing gunpowder.
