Flag flying war memorials litter the center of Ho Chi Minh City, which is what the Vietnamese renamed Saigon after the American War. Most of these memorials feature captured American war materiel, such as intact helicopters, jet fighters, tanks and artillery pieces. You’ll run across them in parks, in the front yards of the aforementioned government buildings, and, of course, at the war museum sites.
The most visited tourist site in the city is the War Remnants Museum. The Museum used to be called the Museum of American War Atrocities.
