Jami' al-Tawrizi, located in the Damascus quarter of Bab Srijeh (Bab al-Sarija), takes its name from Khalil al-Tawrizi, a Mamluk Amir and Grand Chamberlain (hajib al-hujjab) who commissioned the project in 1420/823 AH. The mosque, which was inaugurated in 1423/826 AH includes a prayer hall and mausoleum. A minaret, separated from the mosque, is dated by an inscription to 1428-1429/832 AH. A bath, also named after Tawrizi, was opened nearby approximately twenty years later.

The mosque-mausoleum has been considered one of the first distinctive works of the post-Mongol period. Its plan departs from the traditional Syrian form, adopting a three aisle prayer-hall of Cairene influence. The entrance portal also departs from the traditions of its antecedents, featuring fan-shaped elements in alternating colored stone, rather than the more traditional muqarnas hood. The minaret, however, conforms to a typical Syrian square design. In the tomb and mosque's interior, there are a series of 1,362 hexagonal and triangular faience tiles, dating to the 15th century/8th century AH, in addition to contrasting stonework and inscriptions around the mihrab.
