Thonburi Palace, also known in Thai as Phra Racha Wang Derm, is the former royal palace of King Taksin, who ruled the Siamese kingdom of Thonburi following the fall of Ayutthaya in 1767 and up until the establishment of Rattanakosin in 1782. It later served as the residence of several high-ranking members of the Chakri dynasty until 1900 when the palace became the site of the Royal Thai Naval Academy.
