Ba Đình is the political center of Vietnam. Most of the government offices and embassies are located here including the most important sites of the Vietnamese state such as the Ba Đình Square, the Presidential Palace, the National Assembly Building, the Government Office and the Communist Party of Vietnam central headquarter. It was formerly called the "French Quarter" (Khu phố Pháp) because of a high concentration of French-styled villas and government buildings built when Hanoi was the capital of French Indochina. This name is still used in travel literature. The southern half of Hoàn Kiếm district is also called the "French Quarter", also because of numerous French-styled buildings, most of which are now used as foreign embassies.
