Sightseeing in Washington D.C. picture - Three unknown servicemen are buried at the Tomb of the Unknowns, which opened to the public in 1932, & is guarded by the U.S. Army 24 hours a day, 365 days a year. Made from 7 pieces of Yule marble quarried in Colorado, with a total weight of 79 tons, the Tomb is one of the most-visited sites at the Cemetery. The unknown soldiers include one from the Korean war, and one each from WWI & II. A Vietnam Unknown was also buried there, but the remains were disinterred in 1998 when they were identified, and his family re-interred him near their home. They have since decided that the Vietnam Unknown crypt will remain empty.
