Boyd’s Bible Dictionary:

(Troad). Alexandria Troas, or in the Troad, was an important city in Mysia, Asia Minor, 6 miles south of the entrance to the Hellespont and 4 from the site of Ancient Troy. It was founded by Alexander the Great and was for many centuries the key of commerce between Europe and Asia. Paul visited it more than once (Acts 16:8-11; 20:5-108And they passing by Mysia came down to Troas. 9And a vision appeared to Paul in the night; There stood a man of Macedonia, and prayed him, saying, Come over into Macedonia, and help us. 10And after he had seen the vision, immediately we endeavored to go into Macedonia, assuredly gathering that the Lord had called us for to preach the gospel unto them. 11Therefore loosing from Troas, we came with a straight course to Samothracia, and the next day to Neapolis; (Acts 16:8‑11)
5These going before tarried for us at Troas. 6And we sailed away from Philippi after the days of unleavened bread, and came unto them to Troas in five days; where we abode seven days. 7And upon the first day of the week, when the disciples came together to break bread, Paul preached unto them, ready to depart on the morrow; and continued his speech until midnight. 8And there were many lights in the upper chamber, where they were gathered together. 9And there sat in a window a certain young man named Eutychus, being fallen into a deep sleep: and as Paul was long preaching, he sunk down with sleep, and fell down from the third loft, and was taken up dead. 10And Paul went down, and fell on him, and embracing him said, Trouble not yourselves; for his life is in him. (Acts 20:5‑10)
