Hoàn Kiếm (Vietnamese: {{linktext|還|劍;) is one of the four original urban districts (quận) of Hanoi, the capital city of Vietnam.[3] It is named after the scenic Hoàn Kiếm Lake. The lake is in the heart of the district and serves as the focal point of the city's public life. The majority of tourist attractions in Hanoi are also located in the district.
The district currently has 18 wards (phường), covering a total area of .[1] As of 2019,[2] there were 135,618 people residing in the district
Hoàn Kiếm is the downtown and commercial center of Hanoi. Most of the largest Vietnamese public corporations and bank headquarters are located here, but the central government offices are located in Ba Đình district. The Hanoi Metropolitan People's Committee is located on Đinh Tiên Hoàng street, adjacent to the Hoàn Kiếm lake.
The district has a north–south division among its wards. Its northern half houses the Old Quarter with small street blocks and alleys, and a traditional Vietnamese atmosphere. The southern half has distinctive French-style villas and broad avenues, and is sometimes called the "French Quarter" in modern travel literature. Some notable buildings in Hoàn Kiếm's "French Quarter" are the Hanoi Opera House, the Sofitel Legend Metropole Hanoi hotel, the National Museum of Vietnamese History (formerly the École française d'Extrême-Orient), the Grand Palais, and the Tonkin Palace.
The district has been witness to the long history of Hanoi.
In the early Lý dynasty, in 545, the emperor Lý Nam Đế settled his encampment, and built a wooden raft on the Tô Lịch River to defend against invasion of the Liang dynasty.
During the Nguyễn dynasty, Emperor Minh Mạng established the province of Hanoi in Hoàn Kiếm in 1831.
Between 1954 and 1961, the current district covered all of Hoàn Kiếm ward, Đồng Xuân ward and a part of Hàng Co ward and Hàng Bài ward. In 1961, the entire area was combined into Hoàn Kiếm ward. In January 1981 the ward was upgraded into Hoàn Kiếm district, including 18 wards that have remained since.
The district has a distinctive north–south division among its wards. Its northern-half houses the Old Quarter with small street blocks and alleys, and a traditional Vietnamese atmosphere. Many streets in the Old Quarter have names signifying the goods ("hàng") the local merchants were or are specialized in. For example, "Hàng Bạc" (silver stores) still have many stores specializing in trading silver and jewelries.
Hoàn Kiếm's southern-half has distinctive French-style villas and broad avenues, and is sometimes called the "French Quarter" in modern travel literature. Some notable buildings in Hoàn Kiếm's "French Quarter" are the Hanoi Opera House, the Sofitel Legend Metropole Hanoi hotel, the National Museum of Vietnamese History (formerly the École française d'Extrême-Orient), and the Tonkin Palace. Many of the French-styled buildings in the south of the districts are now used as foreign embassies and government offices. Ba Đình district is also called the "French Quarter" because of the high concentration of French architecture.
Many of Hanoi's tourist attractions are located in Hoàn Kiếm, including the Old Quarter, the Hanoi Opera House, the St. Joseph's Cathedral, the National Museum of Vietnamese History, and the Thăng Long Water Puppet Theatre.
