ARLINGTON NATIONAL CEMETERY
Our national cemetery is 624 acres and shelters the remains of over 320,000 servicemen and women, veterans from every war and major conflict in US history.  The Tomb of the Unknown Soldiers was established in 1921 and has become a memorial icon.  When we were there, the changing of the guard ceremony was held every 30 minutes.  A sentinel maintains vigil around the clock.  The sentinel paces 21 steps alongside the tomb, pauses 21 seconds, then returns.

The cemetery is meticulously maintained and contains many types of trees and vegetation.  This is the one area in DC where the Cherry Blossoms were still in full bloom.
