The White Tower seems to be immensely popular. Why so? Probably because every stone on its six-storie, 34 meters height and 70 meters perimeter happens to be marked by history. One of the most symbolic buildings in the whole Greek territory, the White Tower was constructed in the 15th century as a fortress for the Turkish Gennitsaroi army squad, and was later used as a prison, named “Blood Tower” for reasons that need no explaining. Today, the museum operates as a panorama of the city’s past and present, helped by audio-visual applications, touch-screen multimedia and panels which explain what used to exist in the place of what exists today. Difficult a task as it is, to present a thorough profile of Thessaloniki, with its 23 centuries history, the White Tower museum manages well, despite the limited number of objects displayed.
