This palace's well-preserved buildings, completed between 1665 and 1677, have been converted into museums. Surrounding the buildings are castellated walls and triumphal archways grand enough to admit an entourage mounted on elephants. The most elaborate structure is the Dusit Mahaprasat Hall, built by King Narai to receive foreign ambassadors. The roof is gone, but you can spot the mixture of architectural styles: the square doors are Thai and the domed arches are Western.
North of Phra Narai Ratchaniwet is the restored Wat Sao Thong Thong.
