Caucasian rugs are primarily produced as village productions rather than city pieces. Made from materials particular to individual tribal provinces, the rugs of the Caucasus normally display bold geometric designs in primary colours. Styles typical to the Caucasus region are Daghestan, Shirvan, Gendje rugs, Kazakh and Quba rugs. Several carpet styles from contemporary northwestern Iran also fall largely into this bracket, such as the Ardabil rugs.
