The Singing Marsh is noted in the expanded city mapp accompanying The Compleat Ankh-Morpork and appears to be an urban swamp. No, not the sort of urban swamp represented by The Shades or Shamlegger Street. A natural swamp, which explains why it has largely been left untouched and has not been built on. It occupies a spit of land in a bend of the river Ankh and is to be found on the Mapp in reference square *E2. Its near proximity to Mort Lake and its being bounded by the river on three sides probably explains why it is a marsh, although several footpaths cross it and its riverside edge is firm enough to support a public thoroughfare, Marsh Bank Walk. The landward border is Swansong Way.
