There are many water channels in the infrastructure of the Agora of Smyrna, and two of them are still in operation. There are also springs in the city and settlements. During the Roman period, a canal was built to convey the water flowing from the springs to the lower districts of the city or to the districts where water was scarce. Today, water still flows from the canal that reaches the Agora.
It was also used as a cemetery and prayer place during the Ottoman period. The first excavations in the area were carried out in 1932. İzmir Agora was included in the World Heritage Tentative List as a part of the heritage area created by UNESCO in 2020 as "İzmir Historical Port City".
