An important archaeological site for the prefecture of Kilkis is the one uncovered in Palatiano, a small village north of Kilkis. Remains of a large Macedonian city of the Hellenistic and Roman periods were found in the region. The city might be identified with the ancient Ioron.Excavations at Palatiano began in 1961 and so far have brought to light four impressive statues that are on display in the Archaeological Museum of Kilkis, while copies exist in the area that they were discovered. Ruins of buildings, chapels, and the cemetery of the city were found there. The area of Palatiano can only be visited after consultation with the Archaeological Service.
