Through the Nádasdy family, the castle of Sárvár, now called Nádasdy Castle, played a significant role in the progress of Hungarian culture in the 16th and 17th centuries. The first Hungarian book, The New Testament of 1541, was printed here. The knight's hall of the castle is decorated with the battle scenes of Lord Chief Justice Ferenc Nádasdy (married to the notorious Elizabeth Báthory) and with scenes from the Old Testament.
