The Lydia Kingdom, which had an important role in the social, political, and economic life of Western Anatolian in the Archaic Period, influenced the Hellenic settlements located on the coasts of Ionia as well as the Sardes based administrative area during the 7th century BC. Herodotus posts detailed information about the Lydians, their culture and their relationship with their neighbours. The Lydian pressure on the Ionian coasts which started with King Gyges, has made itself understood strongly for the last time with the attack of King Alyattes in the 600 BC. As it is reported by Herodotus and Strabo, the most effected settlement from this expedition was Old Smyrna. Since the 1930s, in Old Smyrna, where the investigations are carried out intermittently, researchers made interpretations about the destruction caused by Alyattes in the settlement with many archaeological data. The areas where the traces of this destruction can be detected are the aggregate mound which is defined as the siege ramp located on the northwest corner of the city, the phases of the Temple of Athena, which is thought to have been destroyed by the Alyattes’ attack, and the civilian area. With the extensive research in these areas between 1948-51, British and Turkish teams worked to determine the date of the ers made interpretations about the destruction caused by Alyattes in the settlement with many archaeological data. The areas where the traces of this destruction can be detected are the aggregate mound which is defined as the siege ramp located on the northwest corner of the city, the phases of the Temple of Athena, which is thought to have been destroyed by the Alyattes’ attack, and the civilian area. With the extensive research in these areas between 1948-51, British and Turkish teams worked to determine the date of the destruction of Smyrna by Alyattes and they made different interpretations on the archaeological data obtained. Despite this, both teams agreed on the year around 600 BC. Current research made it possible to make new interpretations on the date of the destruction, thanks to the graves and structures located in front of the third defensive wall which was built in the second half of the 7th century BC. In this study, the data and comments about dating the destruction of Smyrna by Alyattes are reviewed, the reliability of the determination of the destruction date has been discussed with these results and it is aimed to contribute to the date of the destruction of Alyattes with current research and the new data which is obtained outside the defensive wall.
