Midway between Cha-am and Hua Hin is Phra Ratchaniwet Marukhathayawan, a summer palace built during the reign of Rama VI. The one- and two-storey buildings are constructed of teak and interlinked by covered boardwalks, all high above the ground on stilts. Incorporating high tiled roofs and tall shuttered windows, the design maximises air circulation.
