Tro'as. The city from which St. Paul first sailed, in consequence of a divine intimation, to carry the gospel from Asia to Europe. Acts 16:8; Acts 16:11. It is mentioned on other occasions. Acts 20:5-6; 2 Corinthians 2:12-13; 2 Timothy 4:13. Its full name was Alexandria Troas, (Liv. Xxxv. 42), and sometimes it was called simply, Alexandria; sometimes simply, Troas.
It was first built by Antigonus, under the name of Antigonea Troas, and peopled with the inhabitants of some neighboring cities. Afterward, it was embellished by Lysimachus, and named, Alexandria Troas. Its situation was on the coast of Mysia, opposite the southeast extremity of the island of Tenedos. Under the Romans, it was one of the most important towns of the province of Asia. In the time of St. Paul, it was a colonia with the Jus Italicum. The modern name is Eski-Stamboul, with considerable ruins. We can still trace the harbor in a basin, about 400 feet long and 200 feet broad.
