Some useful information on the most interesting places to visit in Thessaloniki.

Located in the northeastern of Greece, Thessaloniki is the second-largest city of the peninsula and the capital of the region of Central Macedonia. As second major economic, industrial, and political centre, its port plays a primary role in the Greek economy but also the southeastern European hinterland's one. Its White Tower, sign of the city's ancient fortification, is the symbol of Thessaloniki that has been converted to a museum hosting outstanding collections about the Byzantine history of the city. Towards the town center, visit the Palace of Galerius and appreciate its renowned mosaics and the Galerius arch called Kamára, as well as the Rotunda, an imposing circular dome building known for its impressive Early Christian mosaics from late 4th century B.C. Then do not miss one of the most popular promenade area across the seafront in Nikis Avenue, extending from the port up to the Statue of Alexander the Great to visit stores and have a fresh drink.
