Dusit Palace (Thai: พระราชวังดุสิต, Phra Ratcha Wang Dusit) is a compound of royal residences in Bangkok, Thailand. Constructed over a large area north of Rattanakosin Island between 1897 and 1901 by King Chulalongkorn (Rama V). The palace, originally called Wang Suan Dusit or Dusit Garden Palace (วังสวนดุสิต), eventually became the primary (but not official) place of residence of the King of Thailand, including King Rama V, King Vajiravudh (Rama VI), King Prajadhipok (Rama VII) and King Bhumibol Adulyadej (Rama IX). The palace covers an area of over 64,749 square metres (696,950 sq ft) and is dotted between gardens and lawns with 13 different royal residences. Dusit Palace is surrounded by Ratchwithi Road in the north, Sri Ayutthaya Road in the south, Rachasima Road in the west and U-Thong Nai Road on the east.
Since 1782 and the foundation of Bangkok as the capital city of the Kingdom of Siam, the monarchs of the Chakri Dynasty has resided at the Grand Palace by the Chao Phraya river. The palace became the focal point of the city as well as a seat of the royal government and the home of the king and his court (his children and his polygamous household). During the reign of King Chulalongkorn, the Grand Palace went through a great transformation, with massive reconstructions and additions being made in the main Middle Court (state buildings) and the Inner Court (residential buildings) of the palace. These changes were brought about as a means to modernize the palace as well as accommodate its growing population. As a result, the palace, particularly the Inner Court, became extremely overcrowded. The Grand Palace also became stiflingly hot during the summer months, with the passage of air being blocked by the closely clustered new buildings. Epidemics once started, were liable to spread easily within its crowded compound. The king, who enjoyed taking long walks for exercise and pleasure, often felt unwell after prolonged stays inside the Grand Palace. Consequently, he took frequent trips into the country to take relief of this condition.
