Wizards' Quarter
From Discworld & Pratchett Wiki
The former name for the district of Ankh-Morpork comprising Unseen University, Sator Square and the Unreal Estate. It is now generally known by this latter title. In The Colour of Magic, it's also called "Magician's Quarter" and "Magical Quarter". In the center of said quarter is the Tower of Art, a huge, ugly tower that Rincewind has the pleasure of entering in The Light Fantastic. One can refer to it either as the Wizards Quarter, Magical Quarter, or Magicians Quarter, though it is possible that the latter two titles imply other people of magic live there besides wizards. (Such as magicians, mages, and alchemists.)
Alchemists are of course entirely unmagical.
