Vimanmek Mansion is the worlds largest golden teakwood mansion with its elaborate architectural style reflecting a western influence. It was built in 1900 by King Rama V by having the Munthatu Rattanaroj Residence in Chuthathuj Rachathan at Ko Sichang, Chonburi, dismantled and reassembled in Dusit Garden. Not a single nail was used during its construction. The celebration for the completion of the 72 room Vimanmek Palace was held on March 27, 1901. It was used as a royal palace by King Rama V for five years until the completion of Amphorn Satharn Villa in 1906. In 1932, Vimanmek Palace was used only as a storage place of the Bureau of the Royal Household.
The building has two right-angled wings, each wing 60 meters long and meters high, and is three-storied except for the part where King Rama V resided, which is octagonal and four-storied. Although the ground floor is brick and cement, the upper floors are built of beautiful golden teakwood. Altogether there are 31 exhibition rooms, with the bedrooms, the throne room and the bathrooms maintaining the atmosphere of the Thai past. Some display rooms house exhibitions of Thai art including silverware, ceramics, crystal ware, and ivory.
