tro'-as (Troas): The chief city in the Northwest of Asia Minor, on the coast of Mysia in the Roman province of Asia. From here, according to Acts 16:8, Paul sailed. Here, also, according to Acts 20:5-12, Paul raised Eutychus from the dead. The name Troas was not confined to the town itself, but it was also applied to the surrounding district, or to that part of the coast which is now generally known as the Troad. In its early history it bore the name of Antigona Troas, which was given it by its founder Antigonus, but after 300 B.C. it was generally known to the classical writers as Alexander Troas, a name given to it by Lysimachus. For a time the Seleucid kings made their homes at Troas. Later, when the city became free, it struck its own coins, of which vast numbers are found; a common type is one upon which is stamped a grazing horse. In 133 B.C. Troas came into the possession of the Romans, and later, during the reign of Augustus, it was made a Roman colonia, independent of the Roman governor of the province of Asia. Its citizens were then exempt from poll and land tax. During Byzantine times Troas was the seat of a bishopric.
The ruins of Troas, now bearing the name of Eski Stambul, are extensive, giving evidence of the great size and importance of the ancient city. They have, however, long been used as a quarry, and the columns of the public buildings were taken to Constantinople for use in the construction of the mosque known as the Yeni Valideh Jami. The site is now mostly overgrown with oaks, but from the higher portions of the ruins there is an extensive view over the sea and the neighboring islands. It is only with difficulty that one may now trace the city walls and locate the square towers which flanked them at intervals. Within the walls are the remains of theater, the temple and the gymnasium, which was provided with baths. The port from which Paul sailed was constructed by means of a mole, with an outer and an inner basin. The most imposing of the ruins, however, is a large aqueduct which was built in the time of Trajan.
