France withdrew from Vietnam after signing the Geneva Agreement in 1954. In September of the same year, it handed over "Norodom Palace" to Wu Tingyan Puppet Regime in Saigon, renamed "Independent Palace". On July 27, 1962, two anti-war pilots belonging to Saigon's puppet regime drove a plane to drop bombs on the "Independent Palace" and partially collapsed it. At the end of 1962, Saigon's puppet regime was rebuilt, expanding its area and building solid defense facilities, such as basements and roof platforms for helicopters to land on. On April 30, 1975, the Battle of Ho Chi Minh ended and Saigon was liberated. According to the decision of the Vietnamese National Unification Political Consultative Conference, since November 1975, "Independence Palace" has been renamed "Unification Palace" as a symbol of the Vietnamese people's will to strive for independence and unity. The Palace of Unification was built in 1966. It is a huge four-storey white building with an area of 120,000 square meters. It is the seat of the presidential palace of the former South Vietnamese regime. There are 100 magnificent and magnificent halls in the building, which can meet the needs of diplomacy, banquet, entertainment, residence, military command and so on. Like architecture, the courtyard design uses symmetrical layout, which corresponds to each other and is integrated.
