Tepe Sialk is a large ancient archeological site in a suburb of the city of Kashan, Isfahan Province, in central Iran, close to Fin Garden. The culture that inhabited this area has been linked to the Zayandeh River Culture. The Sialk ziggurat was built around the 3000 BC. A joint study between Iran’s Cultural Heritage Organization and the Louvre verifies the oldest settlements in Sialk to date back to 5500–6000 BC. Tepe Sialk was excavated for three seasons (1933, 1934, and 1937) by a team headed by Roman Ghirshman and his wife Tania Ghirshman.
