Alexandria Troas - A settlement in Troas
Alexandria Troas is the site of an ancient Greek city situated on the Aegean Sea near the northern tip of Turkey's western coast.

According to Strabo, this site was first called Sigeia; around 306 BC Antigonus refounded the city as the much-expanded Antigonia Troas by settling the people of five other towns in Sigeia, including the once influential city of Neandreia. It did not receive its name until its name was changed by Lysimachus to Alexandria Troas, in 301 BC, in memory of Alexander III.

As the chief port of north-west Asia Minor, the place prospered greatly in Roman times, becoming a "free and autonomous city" as early as 188 BC, and the existing remains sufficiently attest its former importance. In its heyday the city may have had a population of about 100,000. Strabo mentions that a Roman colony was created at the location in the reign of Augustus, named Colonia Alexandria Augusta Troas. Augustus, Hadrian and the rich grammarian Herodes Atticus contributed greatly to its embellishment; the aqueduct still preserved is due to the latter. Constantine considered making Troas the capital of the Roman Empire.

It is unknown when the city was destroyed, but it continued to exist at least into thr 10th Century.
