The first signs of urbanism in Cheshmeh Ali, which includes the ancient hill, the ancient towers and raindrops of Rey and the underground spring, are associated with the construction of red pottery with black or brown maps and the paintings on it.
Drying of carpets on the rocky hill of Cheshmeh Ali 1339 solar - the remnants of the Ray Barwi wall can be seen at the top of the photo. This wall has already been restored.
Next to the spring is a hill that was excavated between 1313 and 1315 by Eric Schmidt for the Museum of Fine Arts in Boston and Philadelphia in the United States. Eric Schmidt explored more than six hundred square meters around Cheshme Ali in three consecutive seasons between 1313 and 1315. The oldest signs in this section date back to the beginning of the fourth millennium BC. The result was that three periods of cultural engineering included the layers and symbols of Islamic, Parthian, and prehistoric periods. Thousands of items that Schmidt found in Cheshme Ali are now housed in US treasures and universities, and a small portion of them are housed in the Museum of Ancient Iran. With the death of Eric Schmidt, his research remained incomplete, and since he knew that the codes for numbering were the only ones he had found, no one had succeeded in reading them, and only a few news reports remained. In 1998, a group from the Cultural Heritage, Handicrafts and Tourism Organization of the University of Tehran and the University of Bradford explored Cheshmeh Ali Hill with the aim of dating its ancient layers. Trenches 2 meters by 5 meters east and west of the hill were formed, and up to a depth of 10 meters, the cultural signs of the sixth, fifth, and fourth millennia before the birth appeared. From time immemorial, the present hill is a great spring for the Neolithic, transitional and ancient Collective cultural periods.
Here, in the third millennium BC, it was suddenly abandoned and returned from the second millennium.
Signs from the Parthian period (the wall of the temple of Anahita belonging to the early Christian period), Sassanids and Islam up to the Timurid period are also found here.
According to various statements, Zarathustra's mother was also born here. It is said that the spring water is provided by Jajrud and Qeytariyeh and after passing through the underground roads, it boils from the heart of the hill
