It is a landmark building in Thessaloniki, the second largest city in Greece. The 34 meter high tower is located at the end of the city's seaside promenade and is one of the most famous landmarks in the city. It can be traced back to the Ottoman Empire period, initially built as a defensive fortification and later used as a prison and execution site, witnessing the suffering and history of Thessaloniki. Nowadays, the White Tower has been transformed into a museum and cultural center, showcasing the history of Thessaloniki from the Ottoman Empire period to modern times. The exterior walls were painted white, symbolizing peace and rebirth, becoming a symbol of free thought and culture in Thessaloniki.
