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 western north-south corridor, called the Westward Expansion corridor, includes maps and scenes showing the growth of the United States from early exploration through the acquisition of Alaska and Hawaii.
