"The Maiden’s Tower, which seemingly floats in the Bosphorus off Asia, is one of the more popular symbols of the city. Once a Byzantine tollbooth and later an Ottoman lighthouse, it’s most famous for a legend involving a princess and a prophecy that she would die from a snakebite. Her father exiled her to the tower in the hope of protecting her but, alas, the prophecy could not be avoided—a snake made its way to the island, either in a bouquet of flowers or a basket of grapes (depending on the version of the tale)."
