Thessaloniki is Greece's second-largest city and the capital of the Greek region of Macedonia and the periphery of Central Macedonia. Thessaloniki is commonly called the 'Symprotevousa' (lit. co-capital) of Greece since the National Schism, due to its heritage as the 'symbasileousa' (co-queen) of the Byzantine Empire. According to official data, the Thessaloniki Urban Area curves round the Thermaic Gulf for approximately 17 km; it comprises 16 municipalities and according to the 2001 census it has a population of 1.889,746.

Its commercial port is of a great importance for Greece and for its southeast European hinterland. The city has two state universities that host the largest student population in Greece. As a cultural center, it is renowned for its large number of monuments of Byzantine architecture as well as for some main Ottoman, and Jewish structures. The city is famous for its International Trade Fair which takes place at the beginning of every September and it is the place where the Prime Minister of Greece gives a major speech to announce the governmental plans for the year to come.
