Phra Chuthathut Palace

Phra Chuthathut Palace is a former royal summer palace on Ko Sichang Island in Tha Thewawong, Ko Sichang District, Chonburi Province, Thailand. Built during the reign of King Chulalongkorn (Rama V) between 1888 and 1893, it is the only royal palace located on an island in Thailand. The complex features Thai-European wooden buildings, landscaped gardens overlooking the Gulf of Thailand, and a museum displaying royal artifacts and photographs.

Visitors can explore a restored royal palace complex set on a hillside overlooking the sea on Ko Sichang Island. The site includes well-preserved teak buildings in Thai and European styles, including the Vadhana Building, exhibition halls with historical photographs and artifacts, manicured gardens, ponds and sea-view pavilions. Paths connect the buildings through shaded grounds, with interpretive displays about royal use and architecture. The atmosphere is quiet and museum-like, suitable for walking and photography.

Built between 1888 and 1893 during the reign of King Chulalongkorn (Rama V) as a summer palace on Ko Sichang Island. Named after Prince Chuthathut, a son of the king born on the island. Construction was halted in 1893 and the palace was later abandoned. Several buildings were relocated, including one now part of Vimanmek Mansion in Bangkok. The remaining complex was later restored and preserved as a museum under the care of Chulalongkorn University.
