At the end of the month, we mark the centennial of the Lincoln Memorial. This monument to our 16th President was dedicated on Memorial Day (then Decoration Day) in 1922 and its one hundred year birthday falls on Memorial Day this year. The Lincoln Memorial is visited by millions every year in Washington, D.C., and has been the site for many memorable speeches and events over time.  The dedication ceremony drew quite a crowd. On May 30, 1922, approximately 50,000 people gathered around the base of the memorial and some along the Reflecting Pool, as seen in the photos below: Dedication Lincoln Memorial, [5/30/22].
