The third obelisk is the Washington Monument, built to commemorate our First President, George Washington. In light of the symbols which we have just studied, which have been built into the layout of Government Center, I believe the Washington Monument was constructed by Masons, according to Masonic tradition, as a symbol that this country was controlled by Freemasonry from the very beginning.
