U.S. Capitol Dome Restoration Project

The Dome of the U.S. Capitol Building, one of America’s great symbols of freedom, needs additional restoration as part of an on-going multi-phased program. This project is a critical step for stopping the current level of deterioration in the Dome’s cast iron as well as ensuring the protection of the interior of the Dome and Rotunda. The restoration project includes removal of old paint, repairs to the cast iron and stone, and repainting. Learn more about the Dome Restoration Project.
