Capitol tunnels and subway versus 'secret' passageway myths

The U.S. Capitol is connected to nearby congressional office buildings and the Capitol Visitor Center by a documented network of underground pedestrian tunnels and a small Capitol subway used to move Members and staff. Popular myths describe extensive secret passageways beneath the Capitol, but the existence and basic layout of the Capitol tunnels and subway are public and managed with restricted access for security. The tunnels are operational infrastructure rather than the hidden conspiratorial routes often portrayed in folklore.
