Viaduct

The viudict is a part of Warner Brothers' model of Hogwarts Castle. It is constructed of stone, and extends all the way down to the lake. In the films, a courtyard outside the Entrance Hall contains an archway which leads to the Paved Courtyard and across to the viaduct. At the other end, there are double doors which lead into another entrance room. It should be noted that the viaduct does not exist in the books at all, but is depicted in most of the pictures of Warner Brothers' model of the castle.
