White Tower of Thessaloniki - Physical Attributes

Physical Attributes

The White Tower takes the form of a cylindrical drum 23 m (75 ft) in diameter with a height of 27 m (89 ft) above ground level, on top of which is a turret 12 m (39 ft) in diameter and 6 m (20 ft) high. Some of the embrasures in the outer wall of the tower are reached by a spiral ramp; others are accessed from a central room on each of the six floors. The turret houses a platform with a diameter of 10 m (33 ft), and the platform at the top of the main tower in front of the turret is about 5 m (16 ft) wide.

The tower has been altered substantially over the years. Early illustrations show that it was originally covered by a conical roof, like similar towers in the Yedikule Fortress and Rumelihisarı fortress in Istanbul. Until its demolition in 1917, a chemise stood at the foot of the tower, supporting the heavy guns and enclosing an area at least three times the diameter of the main tower. Octagonal turrets on the chemise and caponiers at ground level provided flanking fire around the tower. It is unclear whether the chemise was part of the original scheme for the tower or was a later addition.
