The late president’s grave is located in mausoleum of Ho Chi Minh in Ba-Dinh Square and Hung Vuong Street, in western Hanoi. It was built with Russian help between 1973 and 1975, on the site where Ho Chi Minh presented the Declaration of Independence on September 2, 1945. The 21-meter-high mausoleum is a dark gray building in the shape of a colossal cube. Marble from the Marble Mountains near Da Nang was used as a building material.
