What is the function of the U.S. Capitol?

The United States Capitol Building houses the meeting chambers of the Senate (in the north wing) and the House of Representatives (in the south wing) – the two bodies that compose the legislative branch of the American government. It also includes the offices of congressional leadership, and it is used for ceremonies of national importance such as presidential inaugurations and the lying in state of eminent persons. The U.S. Capitol is also a museum of American art and history and is visited by millions of people every year.
