The ancient city of Ephesus boasted an advanced aqueduct system that supplied the city with water. The aqueduct is no longer intact, instead, standing as occasional archways which run through the centre of Selcuk. The aqueduct is now famous for the huge stork nests which adorn its top. The migrating storks return to Selcuk during the spring and summer months and reclaim their place in the nests atop the aqueduct.
