U.S. Capitol Dome Restoration Project
The cast-iron dome has been damaged by weather and age
The Dome of the U.S. Capitol building, one of the most recognizable landmarks in the country, is undergoing a multi-year restoration project to repair damage caused by age and weather.
Visitors will notice a few changes: construction supplies and fences have arrived on the Capitol grounds for workers to construct the scaffolding that will surround the Dome. The scaffolding will start going up in the spring.
Tours of the Capitol will be conducted during the two-year project, but visitors should be aware that some areas may be restricted. The rotunda of Capitol will be closed from April 12 until April 28 for the installation of a canopy system, which will protect the public during the restoration.
Constructed of more than 8 million pounds of iron, the Dome has not undergone a complete restoration since 1960. The project, spearheaded by the Architect of the Capitol, will repair cracks that allow air, sunlight, snow, sleet, and rain inside the Dome, which is causing paint to chip and the iron to rust.
More information about the restoration process is available from the Architect of the Capitol.
