The Capitol's first cornerstone was laid on September 18, 1793, by President Washington in a Masonic ceremony. The ceremony was preceded by a parade and followed by celebration and feasting.
About the Cox Corridors Murals
The first floor of the U.S. Capitol's House wing is elaborately decorated with wall and ceiling murals by artist Allyn Cox. The eastern north-south corridor has been termed the Hall of Capitols because it features paintings of 16 different buildings that housed the Continental and United States Congresses from 1754 to 1865. Painted in the barrel vaults of the ceilings are eight historic events that occurred during the first 65 years of the Capitol's existence.
