This is one of the more potent symbols of the Vietnam War. On April 30, 1975, a North Vietnamese Army tank smashed through the main gate of what was then known as the Independence Palace, ending one of the bloodiest conflicts in living memory. The current boxy building replaced the elegant French colonial-style Norodom Palace, which was bombed by fighter jets in 1962 in an unsuccessful attempt to assassinate South Vietnam's President Ngo Dinh Diem. The jet, along with the tanks that ended the war, is on display on the grounds. Free guides are available inside the palace, which remains as it was on that fateful day in 1975, albeit slightly more worn. The time-capsule nature of the palace offers a fascinating insight into the high life of 1960s Saigon, when bigwigs would enjoy tea and movie screenings in plush rooms upstairs, while the war effort was directed from the spartan concrete warren in the basement. The gardens cover 18 hectares (44 acres) of lush lawn and shady trees, and a large fountain in front of the palace redirects the bad luck that could flow into the palace from the broad boulevard of Le Duan Street, according to the principles of feng shui.
