Check Out the Maiden's Tower
Last but not least, as you walk down south along the coast from Üsküdar ferry terminal, you will see the Maiden's Tower is an ancient lighthouse built on a small islet on the Bosphorus strait. The lighthouse was built in the 18th Century which isn't very long ago but that didn't stop a legend about its location and its name to develop among the locals.
According to one version, the lighthouse was constructed by an emperor whose daughter visited an oracle and received a prophecy that she would die at the age of 18 at the hands of a snake. The emperor constructed a tower in the middle of the Bosphorus to keep his daughter safe from this fate. The emperor is the only person who can visit her daughter and on her 18th birthday, to celebrate their success in avoiding the tragedy, the father brought her a fruit basket. Upon reaching the basket, a hidden snake sprung out from the basket, bitted the daughter, and she died in his arms, hence the name Maiden Tower.
