The nicest and most famous room in the Nádasdy Ferenc Museum is the Assembly Hall that was finished in the middle of the 17th century. It was commissioned by the judge Ferenc Nádasdy III whose grandfather intended to remember the famous 'Black Bey' when he had the most outstanding battles his ancestors fought painted on the ceiling by Hans Rudolf Miller of Vienna. The two frescos were finished in 1653 with the figure of the Black Bey on one of them.
