It was located in the suburban outskirts of the city but due to the rapid urbanization of Ho Chi Minh City, the urban area eventually eclipsed the cemetery. There are several illegal houses built in and around the cemetery, and an estimated 300,000 residents live among the tombs. In Vietnamese custom, the dead are often buried and therefore puts the pressure on land near the city, especially a large city like Ho Chi Minh City.

The final offensive against Saigon -- the capital of South Vietnam in 1975 was named after him (the Ho Chi Minh Campaign).

Document 15: Saigon Bridge: Saigon Bridge, known as Newport Bridge () before 1975, is a bridge crossing the Saigon River, connecting Bình Thạnh District and District 2, Ho Chi Minh City, on the Hanoi Highway. The bridge has four lanes for cars and two lanes for motorcycles and bicycles. It was the only bridge linking District 1 to the new Thu Thiem New Urban Area in District 2 until the Thủ Thiêm Bridge opened in 2008 and the Saigon River Tunnel opened in 2011. The bridge was one of the most vital gateways for vehicles traveling from northern and central Vietnam to the city, and therefore was a key point of contention during the Tet Offensive in 1968 and the Fall of Saigon in 1975. In 2013, a new parallel bridge, Saigon 2 Bridge, was opened to ease congestion on the bridge.
