The White Tower of Thessaloniki (Greek: Λευκός Î ÏÏγος Lefkós Pýrgos; Turkish: Beyaz Kule; Ladino: Kuli Blanka) is a monument and museum on the waterfront of the city of Thessaloniki, capital of the region of Macedonia in northern Greece. The present tower replaced an old Byzantine fortification, known to have been mentioned around the 12th century, that the Ottoman Empire reconstructed to fortify the city's harbour sometime after Sultan Murad II captured Thessaloniki in 1430. The tower became a notorious prison and scene of mass executions during the period of Ottoman rule.
The White Tower was substantially remodeled and its exterior was whitewashed after Greece gained control of the city in 1912. It has been adopted as the symbol of the city.
