It is the symbol of Thessaloniki. It was built in the 16th century as a part of the fortifications. It was standing at the spot where the sea wall, demolished in 1867, joined the east wall. It has a total height of 30 metres and a diameter of 70 metres. It consists of 6 floors. In the Ottoman period, the White Tower was a notorious prison and place of execution, thus explaining its name. It was originally called Kanli Koule, the Tower of Blood. In 1890, the tower was whitewashed by a convict in exchange for his freedom, and was henceforth known by its current name. Inside the White Tower, there is now a museum where visitors can enjoy a digital reconstruction of the city’s history.
