Thessaloniki is the capital of the region of Central Macedonia, Greece, and is, at about one million inhabitants, the second largest city in the country. 

More importantly, it is a city with a continuous 3,000-year history, preserving relics of its Roman, Byzantine and Ottoman past and of its formerly dominant Jewish population. Its Byzantine churches, in particular, are included in UNESCO's World Heritage list.

Thessaloniki lies on the northern fringe of the Thermaic Gulf on its eastern coast and is bound by Mount Chortiatis on its southeast. The metropolitan area, with population of about 1 million, can be divided roughly in 3 parts: The northwestern, the central and the southeastern.
