What is "ophryneion"

Ophryneion was an ancient Greek city in the northern Troad region of Anatolia. Its territory was bounded to the west by Rhoiteion and to the east by Dardanos. It was located about 1.5 km north-east of the village of İntepe (previously known as Erenköy) in Çanakkale Province, Turkey. The city was situated on the steep brow of a hill overlooking the Dardanelles, hence the origin of its Ancient Greek name (ophrus), meaning 'brow of a hill', 'crag'.
