The Grand Palace is a complex of buildings in Bangkok, Thailand. It served as the official residence of the Kings of Thailand from the 18th century onwards. Construction of the Palace began in 1782, during the reign of King Rama I, when he moved the capital across the river from Thonburi to Bangkok. The Palace has been constantly expanded and many additional structures were added over time. The present King of Thailand, King Bhumibol Adulyadej, however, resides at the Chitralada Palace.
