King James Bible Dictionary

A city on the coast of Mysia, in the north-west of Asia Minor, named after ancient Troy, which was at some little distance from it (about 4 miles) to the north. Here Paul, on his second missionary journey, saw the vision of a "man of Macedonia," who appeared to him, saying, "Come over, and help us" (Acts 16:8-11). He visited this place also on other occasions, and on one of these visits he left his cloak and some books there (2 Corinthians 2:12; 2 Timothy 4:13). The ruins of Troas extend over many miles, the site being now mostly covered with a forest of oak trees. The modern name of the ruins is Eski Stamboul i.e., Old Constantinople.

Acts 16:8; Acts 16:11; Acts 20:5-6; 2 Corinthians 2:12; 2 Timothy 4:13

the city from which St. Paul first sailed, in consequence of a divine intimation, to carry the gospel from Asia to Europe. (Acts 16:8,11) 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 broad.
