Its construction is thought to have taken place during the Alexandrian period, with repairs being undertaken during the rule of Dimitri the Besieger during the 3rd or 4thcentury A.D. Consisting of three stories, the tower was constructed with large, white marble bricks, which were reinforced by themselves, rather than by metal supports. The surviving section of the tower has an external diameter of of approximately 8.4 metres and a height of 13 metres, though it is originally believed to have reached 13.5 metres. Unfortunately, stairs connecting the stories have bot survived the passing of time.
