Located in Alexandria, VA, the George Washington Masonic National Memorial is dedicated to the memory of America’s most famous freemason. The memorial was completed in 1932 and stands an impressive 333 feet tall.

On the ground in front of the monument is a huge symbol of Freemasonry. Best viewed from the air, this symbol consists of a set-square and compasses, common architect’s tools, and a letter G which is said to be a reference to either geometry or God.
