This building stands on the northwest corner of the intersection of Sharia al-Muski and Sharia al-Mu'izz li-Din Allah in Al-Azhar Square. The lunette of tiles over the door, the minaret above the entrance, and the sabil-kuttab belong to a structure built here by 'Abd al-Rahman Katkhunda in the eighteenth century. They front a much older structure that has undergone so many restorations its real identity can only be speculated upon. This lovely fountain-school is virtually identical with a twin whose main features are fully described farther up the street.
