The Knights’ Hall was rebuilt from the original observation room as part of the Romantic conversion. In the corner of the room a replica of a full plate medieval armour with a sword is displayed (it is a copy from the beginning of the 20^th century). This is how knights dressed and armed rode into battle in the 15^th century. On the walls are installed cold weapons, halberds, spears, a voulge, modified scythes and parts of protective armour, helmets, a shield. The weapons date from the 15^th to the 19^th century. Helmets with movable plates to protect the neck are called ‘lobster-tailed pot helmets’ on the basis of their appearance. They were also nicknamed ‘pappenheimers’ after the Holy Roman Empire marshal Gottfried Heinrich zu Pappenheim, who fought in the Thirty Years’ War (1618–1648), when they were used by heavy cavalry.

In the Knights’ Hall there hangs a chandelier with three oil lamps at the bottom. The executors of count John Pálffy’s last will commissioned it for the interior of the castle tomb, where it was to be placed in front of the altar, illuminated by three oil lamps in the lower part of the chandelier.
