It was constructed in the 12th century, or possibly earlier - its architectural style and construction sequence is obscure, and estimates for its age go back to an unlikely 2,500 years. It was built by the 12th century architect Masud ibn Davud, who was probably the father of the architect of Mardakan Round Tower (not to confuse with Mardakan castle).
There are a number of competing explanations for the name:
A legend concerning a maiden who threw herself off its top, to her death in the waves below.
The fact that the tower has never been taken by force.
Some historians relate it to Oghuz Turks
Some consider that it was once a Watch Tower [Göz Qalası]
