Aigosthena

Aigosthena (Ancient Greek: Αἰγόσθενα) was an ancient Greek fortified port city of Attica, 19 km (12 mi) northwest of the ancient city of Megara to which it belonged. It is also the name of the coastal settlement at the foot of the ancient city walls, also known as Porto Germeno. The ancient citadel retains several of the tallest surviving towers of ancient Greece.
