A Kashan rug is a type of Persian rug from the area of Kashan. Kashan is a city in Isfahan province in North Central Iran, historically known as a major center of the garment trade.
The finest quality rugs from Kashan were called Mohtashem. Today, it is generally assumed that Mohtashem is an indication of fine Kashan workshop production rather than a firm attribution. However, with the existence of some signed Mohtashem rugs it is certain that the workshop existed. The early Kashans were made with Manchester wool and are softer to touch. Some of the best Kashans are from Ardistan and excellent ones are also produced in Yazd and Kashmar in Khorasan.
