Phra Chuthathut Palace

The Phra Chuthathut Palace (Phra Chuthathut Ratchathan) or Sichang Palace (Phra Ratcha Wang Sichang) is a former summer royal residence built during the reign of King Chulalongkorn the Great on the Sichang Island in Chonburi Province. After the French occupied the island during a conflict with Thailand over control of neighboring Laos in 1893, the royal residence was largely abandoned. Parts of the unfinished halls were removed and were used for the new Vimanmek Mansion in Bangkok. Since leaving the royal control, the palace has been used by various affiliations and authorities. Today, Chulalongkorn University occupies the palace for its "Sichang Marine Science Research and Training Station" and established the Chutathut Palace Museum of Chulalongkorn University, maintaining and preserving the palace.
