As the capital of Vietnam for almost a thousand years, Hanoi is considered to be the cultural centre of Vietnam, where every dynasty has left behind their imprint. Even though some relics have not survived through wars and time, the city still has many interesting cultural and historic monuments for visitors and residents alike. Even when the nation's capital moved to Hue under the Nguyen dynasty in 1802, the city of Hanoi continued to flourish, especially after the French took control in 1888 and modeled the city's architecture to their tastes, lending an important aesthetic to the city's rich stylistic heritage. The city boasts more than 1,000 years of history, and that of the past few hundred years has been well preserved.^[9]

Hanoi hosts more cultural sites than any city in Vietnam, including over 600 pagodas and temples.^[10]

The Old Quarter, near Hoan Kiem lake, has the original street layout and architecture of old Hanoi. At the beginning of the 20th century the city consisted of only about 36 streets, most of which are now part of the old quarter. Each street then had merchants and households specialized in a particular trade, such as silk traders, jewelery, etc. The street names nowadays still reflect these specializations, although few of them remain exclusively in their original commerce. The area is famous for its small artisans and merchants, including many silk shops. Local cuisine specialties as well as several clubs and bars can be found here also. A night market (near Đồng Xuân market) in the heart of the district opens for business every Friday, Saturday, and Sunday evening with a variety of clothing, souvenirs and food.

Some others prominent places are: The Temple of Literature (Văn Miếu), site of the oldest university in Vietnam 1070; One Pillar Pagoda (Chùa Một Cột); Flag Tower of Hanoi (Cột cờ Hà Nội). In 2004, a massive part of the 900 year old citadel was discovered in central Hanoi, near the site of Ba Dinh square. ^[11]

A city between the rivers, built from lowland, Hanoi has many scenic lakes and sometime is called "city of lakes". Among its lakes, the most famous are Hoan Kiem Lake, West Lake, Halais Lake (Hồ Thiền Quang) in Vietnamese), and Bay Mau Lake. West Lake (Hồ Tây) is a popular place for people to spend time. It is the largest lake in Hanoi and there are many temples in the area. There are small boats for hire and a floating restaurant.

Under French rule, as an administrative centre for the French colony of Indochina, the French colonial architecture style became dominant, many examples remain today: the tree-lined boulevards (e.g Phan Dinh Phung street), The Grand Opera House, The State Bank of Vietnam (formerly The Bank of Indochina), The Presidential Palace (formerly Place of The Governor-General of French Indochina), the cathédrale St-Joseph, and historic hotel Sofitel Metropole.
