Gia Long Palace (Vietnamese: Dinh Gia Long), now officially the Hồ Chí Minh City Museum (Vietnamese language: Bảo tàng Thành phố Hồ Chí Minh) is a historical site and museum in Hồ Chí Minh City (Saigon), Vietnam. The museum is situated at the corner of Lý Tự Trọng and Nam Kỳ Khởi Nghĩa streets, located on 2 hectares of land, near the Independence Palace.
Construction of the palace began in 1885 and completed in 1890, and was designed by French architect Alfred Foulhoux to house the Museum of Commercial Trade, exhibiting products and goods of Southern Vietnam. However, the building soon became the residence of the Governor of Cochinchina, starting with Henri Éloi Danel (1850 - 1898).
In 1945, control of the palace changed hands several times. After the Japanese Imperial Army toppled the colonial regime of French Indochina on March 9, French governor Ernest Thimothée Hoeffel was arrested, and the palace became the residence for Japanese Governor Yoshio Minoda.
On August 14, the Japanese handed over the palace to its puppet Empire of Vietnam government, to be used as the residence of Lieutenant General Nguyễn Văn Sâm.
On August 25, the Việt Minh seized, arresting Nguyễn Văn Sâm and Secretary of the Office of the Lieutenant General Hồ Văn Ngà. After, the building became the headquarters of the Provisional Administrative Committee of Southern Vietnam, later renamed the "People's Committee of Southern Vietnam".
On September 10, Lt. Col. B. W. Roe (from the British military mission) occupied the palace and made it the Allied Mission headquarters, evicting the "People's Committee".
On October 5, the building was used by General Leclerc as the temporary headquarters of the High Commission for the French Republic in Indochina. After Admiral Georges Thierry d'Argenlieu from the High Commission selected Norodom Palace to be the Commission's new location, the palace was used as Leclerc's office, this time as the official headquarters of the Commissioner of the French Republic in Southern Vietnam.
