The four Dismantling Halls are used to keep the Outer Royal Urn (Phra Kot Thong Yai) and the Sandalwood Royal Urn (Phra Kot Chan) after the inner urn is placed on the funeral pyre (Phra Chittakathan), as well as for keeping various items used in the Royal Cremation Ceremony, such as wood charcoal, sandalwood flowers, and water bowls.
