Way back in 2009 I stumbled across a YouTube video of Senator Alan Simpson (Wyoming), on a 1997 walking tour inside the U.S. Capitol Dome, going all the way to the lighthouse at the base of the Statute of Freedom. Senator Simpson wanted to celebrate his retirement from congress in 1997 by taking one last look at Washington DC through the glass panels of the Tholos, beneath the pedestal of the Statute of Liberty. Personally, I've visited the U.S. Capitol Building at least ten times while I lived on the east coast, but I didn't know it was possible to tour the Capitol Dome from the inside and climb all the way to the uppermost outside balcony.
The Dome itself is a facade of cast iron, made up of an inner dome and an outer dome, painted to look like marble.
A winding stairway between the two domes allows access by maintenance staff, and occasional visitors, to the uppermost reaches of the Capitol Dome's interior and exterior.
The pedestal of the Statute of Freedom rests atop the "Tholos" (Tholus), or lighthouse, at the apex of the Dome. It is illuminated whenever congress is in session after dark.
That old YouTube video is long gone, but I did find CBS reporter Scott Pelley's video tour from 2013, the Capitol Building and the Washington Monument were both undergoing restorations.
