The Persian carpet  is an essential part of Persian art and culture. Carpet-weaving dates back to ancient Persia (modern day Iran). Wool is the most common material for carpets but cotton is frequently used for the foundation of city and workshop carpets.  Silk carpets are less common than wool carpets since silk is more expensive and less durable; they tend to increase in value with age and they are often displayed on the wall like tapestries rather than being used as floor coverings.
