Quirm Memorial
The Quirm Memorial is one of what the The Compleat Discworld Atlas describes as The More Than Seven Wonders Of The World. Unfortunately it was designed by B.S. Johnson and is currently in the keeping of of Mr. Scant, the official Keeper of the Monuments in Ankh-Morpork. It apparently has a link to the Colossus of Morpork, although the exact association is unclear.
