Intotheiran: Kashan and suburbs have a population of 400,000. Kashan is internationally famous for manufacturing carpets, silk and other textiles. Today, Kashan houses most of Iran's mechanized carpet-weaving factories, and has an active marble and copper mining industry. Kashan dates back to the Elamite period of Iran.
The etymology of the city name comes from the Kasian, the original inhabitants of the city, whose remains are found at Tapeh Sialk dating back 9,000 years; later this was changed to "Kashian", hence the town name. Between the 12th and the 14th centuries Kashan was an important centre for the production of high quality pottery and tiles. In modern Persian, the word for a tile (kashi) comes from the name of the town.
Kashan is divided into two parts, mountainous and desert. In the west side, Kashan is cited in the neighbourhood of two of highest peaks of Karkas chain, Mount Gargash to the southwest of Kashan (the home of Iran national observatory, the largest astronomical telescope of Iran) and Mount Ardehaal in the west of Kashan, also known as "Damavand of Kashan" and the highest peak of Ardehaal mountains (end part of Karkas chain in central Iran).
On August 9, 2007 Iran placed the Historical Axis of Fin, Sialk, Kashan on its Tentative List for possible future nomination as a UNESCO World Heritage Site. The exact definition of what locations within Kashan proper might be nominated was not made clear. In 2012 Iran successfully nominated the Fin Garden separately for inscription by UNESCO as a part of its Persian Gardens World Heritage Site. Despite this the "Historical-Cultural Axis of Fin, Sialk, Kashan" remains in full on Iran's Tentative List.
