The Ho Chi Minh Mausoleum (Vietnamese: Lăng Chủ tịch Hồ Chí Minh) is a large memorial in Hanoi, Vietnam. It is located in the centre of Ba Dinh Square, which is the place where Vietminh leader Ho Chi Minh read the Declaration of Independence on September 2, 1945, establishing the Democratic Republic of Vietnam. Construction work began on September 2, 1973, and the structure was formally inaugurated on August 29, 1975. The mausoleum was inspired by Lenin's Mausoleum in Moscow but incorporates distinct Vietnamese architectural elements, such as the sloping roof. The exterior is made of gray granite, while the interior is gray, black, and red polished stone. The mausoleum's portico has the words "Chủ tịch Hồ Chí Minh" (Chairman Ho Chi Minh) inscribed across it.
