Tomb of the Unknown Revolutionary War Soldier The origins of this unique monument date back to the early 1950s, when the Washington Square Planning Committee of Philadelphia discussed the creation of a monument to George Washington. After months of discussion, the committee decided to incorporate the image of Washington into a tribute to all of the Soldiers and Sailors of the Revolutionary War. The monument was named the “Tomb of the Unknown Revolutionary War Soldier” and designed by Edwin Brumbaugh.
