When the Chakraphat Phiman Hall was first built it was entirely roofed with palm leaves; later these were replaced with ceramic tiles, then with glazed tiles during the reign of King Rama V. There is a tradition that no uncrowned kings are allowed to sleep within this hall. However once they were crowned they were required to sleep there, if only for a few nights, literally on the bed of their forefathers.[33][38] In 1910, prior to his coronation, King Rama VI had a well-concealed modern toilet installed near the bedchamber.[39] The king spent many nights here near the end of his life and died here in 1925. King Prajadhipok (Rama VII) and King Rama IX only spent a few nights here after their respective coronations in accordance with tradition.
