The mosque was commissioned during the reign of the Anatolian Seljuk Sultan Gıyaseddin Keyhüsrev III.
The structure features a square layout covered by a central dome, a design common in 13th-century Anatolian mosque architecture.
The building is constructed primarily of cut limestone, typical of the regional Seljuk construction style.
The mosque's minaret was rebuilt in the 20th century following damage sustained in historical conflicts and seismic activity.
It is situated within the Odunpazarı historical urban site, which is currently on the UNESCO World Heritage Tentative List.
