In 1430 the Ottomans constructed the White Tower of Thessaloniki to guard the sea walls. During the years, it became a prison. And now it is the most known monument of the city.
For centuries, the tower was part of the city walls demolished in the middle of the 19th century. Then, after the Greek liberation in 1912, the building was whitewashed to whipping the Ottoman past. This act gave the White Tower his name.
Since then, they have removed the white color and established a small museum dedicated to Thessaloniki and its history. To enjoy all the exhibits, you will have to climb five floors on foot - not easy, but worth it. Don't miss the view from the top of the tower! It's amazing.
