Tepe Sialk site-7500 YEARS

 city, tourism, place with historical importance, archaeological site, historic site

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 first 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. The Fin garden, built in its present form in the 17th century, is a popular tourist attraction. It is here that the kings of the Safavid dynasty would spend their vacations away from their capital cities. It is also here that Piruz Nahavandi (Abu-Lu'lu'ah), the Persian assassin of Caliph Umar, is buried. All these remains are located in the same location where Sialk is.
