Prague Castle is divided into four parts, including the Cathedral of St. Vit, the Old Palace, the Basilica of St. George and the Golden Lane. Tickets are required to enter, and can also be combined, which is also the seat of the Czech presidential palace. The Cathedral of Saint Vit is a typical Gothic building with paintings and stained glass on the walls depicting many allusions, including works by the famous Czech painter Musha. Various chapels within the church have their own characteristics. It is also a cemetery, with the remains of bishops or bohemian rulers buried under the slabs. The old palace was a palace built in the 14th century, and the golden lane is a small alchemy street where Kafka rented. The observation deck near the exit offers panoramic views of Prague's Old Town.
