Sialk Hills, located in the southwestern part of Kashan city in Iran, was known among the locals as a ‘cursed city’ where people were afraid to approach. Before a severe flood led to the discovery of Sialk Hills, no one dared to approach this terrifying location.

Thanks to the flood of 1930, the story of the Sialk Hills, dating back 7500 years to the Achaemenid Period, was also revealed.

In reality, this structure is a ziggurat, a rectangular stepped tower that occasionally has a temple on top and is made primarily of clay; it is possible that calling it “hills” would not be accurate.

It is claimed to be the world’s oldest ziggurat, dating to the 3rd millennium BC, tucked away in the suburbs of the city of Kashan, in central Iran, close to Fin Garden.
