Excavations outside the Damascus city wall near the southeastern Bāb Kīsān gate recovered pottery workshops that manufactured vessels of Alkaline Glazed Earthenwares identical to those discovered in excavations of the city's Citadel, dating to the 10th or 11th century (McPhillips 2012:450, 453). In addition to the production site at the Bāb Kīsān gate, a large potters’ quarter lay outside Bāb Šarqí, the eastern city gate. It includes a large area of kilns likely organized on an industrial level rather than artisanal. While its excavation material and records have been lost, a few photographs of glazed fritware remain and appear to date to the 12th to 15th centuries. That date is supported by a 13th century writer who relates that he was born in the street of the potteries in the Bāb Šarqí neighborhood. A 12th century writer mentions the production of a variety of types of ceramics at two other extramural sites (McPhillips 2012:449-50).
