Why is there a crane at the Capitol building? High in the sky, about 50 feet above the roof, a crane is peeking out of the Cannon House Office Building. This tower crane is part of the Architect of the Capitol's (AOC) 10-year renewal project to improve and preserve the Cannon Building, which has not received a comprehensive systems upgrade since the 1930s.
What is underneath the Capitol building?
The United States Capitol crypt is the large circular room filled with forty neoclassical Doric columns directly beneath the United States Capitol rotunda. It was built originally to support the rotunda as well as offer an entrance to Washington's Tomb.
