The etymology of the city name comes from Kasian, the original inhabitants of the city, whose remains are found at Tapeh Sialk dating back 9,000 years; later this changed to Kashian, whence the town name. Between the 12th and the 14th centuries, Kashan was an important centre for the production of high quality pottery and tiles. Kashan was also a leisure vacation spot for Safavi Kings. Bagh-e Fin (Fin Garden), specifically, is one of the most famous gardens of Iran. This beautiful garden with its pool and orchards was designed for Shah Abbas I as a classical Persian vision of paradise. Archeological discoveries in the Sialk Hillocks, which lie 4 km west of Kashan, reveal that this region was one of the primary centers of civilization in pre-historic ages. Hence Kashan dates back to the Elamite period of Iran. The Sialk ziggurat still stands today in the suburbs of Kashan after 7500 years.
