The streets of Ankh-Morpork

A large folded map of the Discworld's major city, annotated with hundreds of named locations drawn from the novel series. It was created by Terry Pratchett and Stephen Briggs with artwork by Stephen Player and first published in 1993.

Stephen Briggs is a Discworld collaborator best known for his work adapting Discworld novels for the stage, and for co-authoring several companion volumes with Terry Pratchett including maps and encyclopedias.

Not especially — the map is primarily a reference work for existing readers, placing locations mentioned across the novels into a consistent geography. It rewards readers who have accumulated questions about where things are.
