Thessalonike (or more commonly Thessaloniki) is a major seaport city in northern Greece on the Aegean Sea, and the second largest city in the country. Built in 315 BC, it has served as a center of Balkan culture for centuries - Macedonian, Greek, Roman, Byzantine, Ottoman, Bulgarian, Jewish and Roma. In 1910, young Indiana Jones, his parents Henry and Anna, and his tutor Helen Seymour took a steamship voyage from Odessa, Russia to Athens, and their ship stopped in Thessalonike after stopping in Constantinople.
