The museum has been functioning since 1951, and takes its name after the country judge Ferenc Nádasdy, whose collection became famous around Europe in the 17th century. The museum’s most beautiful room is the Great Hall, which alone preserves the glory of the Nádasdy family even in the 21st century. The ceiling frescoes were painted in 1653 and depict the victorious battles of Ferenc Nádasdy, grandfather of the country judge Ferenc Nádasdy who commissioned them. The wall frescoes depicting scenes from the Old Testament are works of István Dorffmeister from 1769.
