The Maiden’s Tower (Turkish: Kız Kulesi), also known as Leander’s Tower (Tower of Leandros) since the Byzantine period, is a tower on a small islet at the southern entrance of the Bosphorus strait, 200 m (220 yd) from the coast of Üsküdar in Istanbul, Turkey. The tower appeared on the reverse of the Turkish 10 lira banknote from 1966 to 1981.
The tower was destroyed during the earthquake of 1509, rebuilt, and then burned down in 1721. Reconstruction was ordered by the grand vizier Damad Ibrahim Pasha and the new building was used as a lighthouse; the surrounding walls were repaired in 1731 and 1734. Then in 1763 the tower was reconstructed in more durable stone. From 1829 it was used as a quarantine station before being restored again by Sultan Mahmud II in 1832. In 1945 it was the turn of the harbour authority to patch it up. Then in 1998 it was restored again, shortly before appearing in the James Bond movie The World Is Not Enough.
After the 17 August 1999 earthquake and tsunami in the Sea of Marmara steel supports were added to the tower to strengthen it. The interior was converted into a café and restaurant, with views of the former Roman, Byzantine and Ottoman capital at Sarayburnu. Private boats ply back and forth between the tower and the shore throughout the day.
In 2021 work on restoring the tower yet again . The work was completed in 2023 and the tower reopened to the public in May of that year.
There are several stories about the tower’s name. According to one of them, an oracle prophesied that the emperor‘s much beloved daughter would be killed by a venomous snake on her eighteenth birthday. To protect her, the emperor had the tower built in the Bosphorus and had her locked up there to keep her away from snakes. Her only regular visitor was her father. On her eighteenh birthday, the emperor brought her a basket of exotic fruits as a gift, delighted that he had been able to thwart the prophecy. However, an asp that had been hiding among the fruit bit the princess who died in her father’s arms, just as the oracle had predicted, hence the name Maiden’s Tower.
