Metropole Hanoi marks 50th Anniversary of U.S.-Vietnam War’s end with special bomb shelter tours. Guests can visit the bunker under the hotel where Joan Baez and others hid during air raids. Sofitel Legend Metropole Hanoi’s special “Path of History” tour includes a visit down into the hotel’s underground bomb shelter, which shielded visitors including Joan Baez, Jane Fonda and others during wartime air raids. The bunker was closed and sealed after the 1964-1975 conflict before being rediscovered by chance during the renovation of the hotel’s Bamboo Bar in 2011. The war ended April 30, 1975.
