The Bishop's Palace was built in the middle of the 14th century and was fortified with walls and a moat. It was rebuilt several times over the course of time. On the main façade of the building are the coats of arms of the bishops who designed the reconstructions until the middle of the 18th century. The palace has been the repository of the Holy Crown of Hungary for several times. In September 1996, Pope John Paul II visited the palace.
The winter suite of the palace is furnished with precious Baroque furniture, while the summer suite features Empire and Biedermeier furniture. A fresco decorates the ceiling of the dining room on the upper floor. Plaster stucco ornaments and scenes from Greek mythology and the Bible can be seen on the walls of several rooms. Two huge vaulted cellars extend under the building.
The first floor of the Baroque staircase, decorated with statues, leads to the chapel of the palace, which was built in 1487. It was named after Bishop Orbán Nagylucsei, chamberlain to King Matthias of Hungary. The interior is in the neo-Gothic style with its three lancet windows and the star vault of the ceiling.
