Thessaloniki is a mosaic of ethnicities, with Greeks, Turks, Jewish, Balkans and Europeans all forming this cosmopolitan, multicultural and unavoidably stimulating city. Apart from the White Tower, the city’s trademark, there are numerous monuments to see and things to do in Thessaloniki, so the city offers itself for a lot of exploring. Less busy than Athens, but still very vibrant, you can see the city’s history in every one of its corners. The Ancient Agora, the Arc of Galerius and the Anaktoro are testaments to the city’s Roman past. The churches of Ayia Sophia, Ayios Dimitrios and Ayios Nikolaos Orfanos tell the stories of Thessaloniki’s Byzantine era. What’s more fascinating is that Thessaloniki is the only city in the world with the most proclaimed World Heritage monuments by UNESCO, from all eras and cultures found in Greece.
