Tepe Sialk (Sialk Hill) is a large ancient archeological site in a suburb of the city of Kashan, Isfahan Province, in central Iran, close to Fin Garden. The Sialk ziggurat was built around the 3000 BC. A joint study between Iran's Cultural Heritage Organization, the Louvre, and the Institut Francais de Recherche en Iran also verifies the oldest settlements in Sialk to date back to 5500–6000 BC. Sialk and the entire area around it, is thought to have originated as a result of the pristine large water sources nearby that still run today. The Cheshmeh ye Soleiman ("Solomon's Spring") has been bringing water to this area from nearby mountains for thousands of years.
