The Grand Palace is a complex of buildings at the heart of Bangkok, Thailand. The palace has been the official residence of the Kings of Siam (and later Thailand) since 1782. The king, his court and his royal government were based on the grounds of the palace until 1925. King Bhumibol Adulyadej (Rama IX), resided at the Chitralada Royal Villa and his successor King Vajiralongkorn (Rama X) at the Amphorn Sathan Residential Hall, both in the Dusit Palace, but the Grand Palace is still used for official events. Several royal ceremonies and state functions are held within the walls of the palace every year. The palace is one of the most popular tourist attractions in Thailand.
Construction of the palace began on 6 May 1782, at the order of King Phutthayotfa Chulalok (Rama I), the founder of the Chakri Dynasty, when he moved the capital city from Thonburi to Bangkok. Throughout successive reigns, many new buildings and structures were added, especially during the reign of King Chulalongkorn (Rama V). By 1925, the king, the Royal Family and the government were no longer permanently settled at the palace, and had moved to other residences. After the abolition of absolute monarchy in 1932, all government agencies completely moved out of the palace.
In shape, the palace complex is roughly rectangular and has a combined area of 218,400 square metres (2,351,000 sq ft), surrounded by four walls. It is situated on the banks of the Chao Phraya River at the heart of the Rattanakosin Island, today in the Phra Nakhon District. The Grand Palace is bordered by Sanam Luang and Na Phra Lan Road to the north, Maharaj Road to the west, Sanamchai Road to the east and Thai Wang Road to the south.
