The Viaduct is a part of Hogwarts Castle. It is constructed of stone, and extends all the way down to the lake. A courtyard outside the Entrance Hall contains an archway that leads to the Paved Courtyard and across to the viaduct. At the other end, there are double doors which lead into the Viaduct Entrance. There were two talking gargoyles at one end of the Viaduct, but unfortunately one was smashed during the 1994 Triwizard Tournament.
