Othello's tower is the medieval fortress or citadel guarding both the harbour and the town of Famagusta. This is referred to in one of Shakespeare's plays in which Othello is described as a Moor. This is not so; it is the name of a Venetian governor of 1506. However, Shakespeare knew little about Cyprus and had never been there. The entrance to the tower is shown in the picture and is pierced through the Venetian fortifications which date from between 1500 and 1550.
Famagusta (Greek: Αμμόχωστος, Ammóchōstos; Turkish: Gazimağusa or Mağusa) is a city on the east coast of Cyprus and is capital of the Famagusta District. It is located in a bay between Capes Greco and Eloea, east of Nicosia, and possesses the deepest harbour in the island. Since the 1974 Turkish invasion the city has resided in the de facto Turkish Republic of Northern Cyprus. The old tourist quarter of Varosha is abandoned pending a settlement of the Cyprus dispute. http://en.wikipedia.org/wiki/Famagusta
