The workers, who are accessing the high dome via a small cage of scaffolding that's been set up around it, also are cleaning and repairing the eagle that tops the dome. The eagle is bronze-plated copper, and with its pedestal, is 5 feet 7 inches high.
Workers who have been cleaning and repairing the state Capitol dome have discovered something interesting as they work on the small dome that sits atop the larger dome, 288 feet up in the air. The smaller dome has a silver coating, but it’s just layers of paint and gunk. It appears that the dome underneath may be made of honey-colored sandstone, just like the rest of the historic building – at least according to “initial scrapings,” says Jan Frew of the state Division of Public Works.
