Alexandria Troas ("Alexandria of the Troad", mod. Eski Stambul) is an ancient Greek city situated on the Aegean Sea near the northern tip of Turkey's western coast, a little south of Tenedos. It is located in the modern Turkish province of Çanakkale. According to the Catholic Encyclopedia, this site was first called Sigia; perhaps about 310 BC Antigonus refounded the city as Antigonia Troas. In its early years, Troas was a port city that supplied the Dorians with resources and trade.
