A late Bronze Age settlement in Panaztepe with a number of tholos tombs indicates an apparent Mycenaean influence. The first nucleus of Menemen was formed on the left bank of the River Gediz in the immediate vicinity of today's Yahşelli village. This settlement dates back to 1000 B.C. and is on the natural fluvial frontier between Ionia and Aeolia of antiquity. It is believed that the settlement was moved from its former place to today's Asarlık village between 263-241 B.C. and later to its actual place during the Turkish principalities era in Anatolia (13th-14th centuries).
