This is said to be one of the most beautiful ceremonial halls of all Hungarian Baroque castles. Crystal mirrors hang on both sides of the hall, reflecting one another and creating the illusion of an infinite place. In the fresco on the ceiling, "The Triumph of Apollo," by J. I. Mildorfer, it's said that wherever you are in the room, the four horses appear to be running towards you. In the time of Prince Nicholas "the Magnificent" this was the most important cultural center in the country. The orchestra that played here was conducted by Joseph Haydn, and some of his most famous works had their premiere in this room, including the "Farewell Symphony."
