Viaduct

The Central Viaduct.

The Central Viaduct was an enormous raised walkway in Sanctaphrax, spanning from The Great Hall to The Loftus Observatory. Two hundred minor schools were erected along the sides of the Viaduct, accessible from the top. The Viaduct was supported by a series of massive arches, under which a system of staircases known as the Viaduct Steps were built.
