Maiden's Tower- İstanbul

It literally means "Maiden's Tower" in Turkish. The name comes from a legend: the Byzantine emperor heard a prophecy telling him that his beloved daughter would die at the age of 18 by a snake. So he decided to put her in this tower built on a rock on the Bosphorus isolated from the land thus no snake could kill her. But she couldn't escape from her destiny after all, a snake hidden in a fruit basket brought from the city bit the princess and killed her.
