One of my favorites follows:
Acts 16:11 ¶ From Troas we put out to sea and sailed straight for Samothrace, and the next day on to Neapolis.
It was at Alexandria Troas (see map below), on Paul’s second missionary journey, that in a vision he received a call to proceed to Macedonia (Acts 16:8–11). Because of the use of “us” it seems that Luke joined Paul and Silas on this portion of the journey.
Troas is a site that is not often visited by visitors to Turkey—yet it is huge — about 1,000(!) acres [405 ha.] in size. It is situated 31.2 mi. [50 km.] northwest of Assos — via the ancient road system. It is 15.5 mi. [25 km.] south of Troy and is largely unexcavated.
There are three parts to the harbor of Troas—from which Paul set sail—the breakwater/quay?, Outer Harbor, and Inner Harbor (see below for pictures of all).
Protruding into the Aegean Sea are the remains of a Breakwater or Quay that protected the entrance of the harbor.
