The historical monument of Sialk Hill is the first civilization in the central part of Iran. Written documents found in Sialk Hill prove its history dating back to the era before Achaemenes. It includes many valuable heritages such as the oldest handmade adobe, Sialk Ziggurat and painted potteries. The ancient people changed their inhabitant from the caves into the plains and through several excavations, the oldest examples are people from Sialk. Sialk Hill was, in fact, the place for worship and it was made of clay. The unique architecture of the pyramid was common among Ziggurat in different cities in Mesopotamia, Sialk Hill is just the same. It is interesting to mention that the first clue of this ancient civilization was found after a flood about eighty years ago. At first, you will see just a sand hill but just stepping in, you will find yourself in a wonderful mysterious land which looks like a tunnel to another world.
