Antique Kashan carpets are among the finest Persian rugs. They are woven in workshops of the city of Kashan, in north central Iran. Kashan was a hub of silk production since the Safavid dynasty, and has created some of the highest quality Persian silk rugs. During the latter part of the 19th century, weavers also began to produce high quality wool rugs and carpets, continuing the high standards of technique and design of the Safavid era.

Among the best Kashan carpets are Mohtasham rugs. They are commonly referred to Kashan-Mohtasham rugs and They frequently have deep and rich color palette and a traditional navy medallion, although all-over designs are rare and not uncommon.
