Concise Bible Dictionary:
Boats in Thessalonica at Sunset
A large and populous city on the sea-coast of Macedonia. Cassander having enlarged it, named it after his wife Thessalonica, the sister of Alexander the Great. Under the Romans it was a city of note, and was eventually made a free city and became the capital of Macedonia. It lay on one of the routes from Rome to the East, and became a great commercial center. This naturally attracted Jews to the place, and they had a synagogue. When Paul had preached there, some Jews and many Greeks believed. It was on Paul’s second and third missionary journeys that he visited them. He wrote the two Epistles to the saints there during his stay at Corinth of a year and a half (Acts 18:11).
Ancient Catacomb in Thessalonica (Thessaloniki)
It is now called Salonika, and is one of the most important cities in European Turkey. Many Jews still reside there (Acts 17:1,11,13; Acts 27:2; Phil. 4:16; 2 Tim. 4:10).
