The President Ho Chi Minh Mausoleum is a mausoleum which serves as the resting place of Vietnamese Revolutionary leader Ho Chi Minh in Hanoi, Vietnam. It is a large building located in the center of Ba Dinh Square, where Ho, Chairman of the Workers' Party of Vietnam from 1951 until his death in 1969, read the Declaration of Independence on 2 September 1945, establishing the Democratic Republic of Vietnam. It is also known as Ba Đình Mausoleum and is open to the public.

The One Pillar Pagoda is a historic Buddhist temple in Hanoi, the capital of Vietnam. It is regarded alongside the Perfume Temple, as one of Vietnam's two most iconic temples.

The Tran Quoc Pagoda in Hanoi is the oldest pagoda in the city, originally constructed in the sixth century during the reign of Emperor Ly Nam De (from 544 until 548), thus giving it an age of more than 1,450 years. When founded the temple was named Khai Quoc (National Founding) and was sited on the shores of the Red River, outside of the Yen Phu Dyke. When confronted with the river's encroachment, the temple was relocated in 1615 to Kim Ngu (Golden Fish) islet of Ho Tay (West Lake) where it is now situated. A small causeway links it to the mainland.

The Old Quarter is the name commonly given to the historical civic urban core of Hanoi, located outside the Imperial Citadel of Thang Long. This quarter used to be the residential, manufacturing and commercial center, where each street was specialized in one specific type of manufacturing or commerce. Another common name referring to approximately the same area is the 36 streets, after the 36 streets or guilds that used to make up the urban area of the city.

The royal enclosure was first built during the Ly dynasty (1010) and subsequently expanded by the Tran, Le and finally the Nguyen dynasty. It remained the seat of the Vietnamese court until 1810, when the Nguyen dynasty chose to move the capital to Hue. The ruins roughly coincide with the Hanoi Citadel today. The royal palaces and most of the structures in Thăng Long were in varying states of disrepair by the late 19th century with the upheaval of the French conquest of Hanoi. By the 20th century many of the remaining structures were torn down. Only in the 21st century are the ruin foundations of Thang Long Imperial City systematically excavated. In mid-1945 the Citadel was used by the Imperial Japanese Army to imprison over 4000 French colonial soldiers captured during the Japanese coup d'état in French Indochina in March 1945. The central sector of the imperial citadel was listed in UNESCO's World Heritage Site on July 31, 2010 at its session in Brazil, as "The Central Sector of the Imperial Citadel of Thăng Long – Hanoi”.

Hoan Kiem Lake, meaning "Lake of the Returned Sword" or "Lake of the Restored Sword"), also known as Hồ Gươm (Sword Lake), is a fresh water lake, measuring some 12 ha in the historical center of Hanoi, the capital city of Vietnam. In the past, the lake was variously name "Luc Thuy Lake", meaning "Green Water Lake" - aptly named for the water's color) or "Thuy Quan Lake", meaning "Mariner's Lake". The lake is one of the major scenic spots in the city and serves as a focal point for its public life.
