Kashan

Kashan is a city in the northern part of Isfahan province, Iran. At the 2017 census, its population was 396,987 in 90,828 families.

Some etymologists argue that 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).
