Ottoman corsairs is another name for the people that the Torra di Tizz was created to protect against.
 The tower was one of a series of coastal defences constructed by the Republic of Genoa between 1530 and 1620 to stem the attacks by Barbary pirates. 
The Barbary pirates, sometimes called Barbary corsairs or Ottoman corsairs, were pirates and privateers who operated from North Africa, based primarily in the ports of Sal, Rabat, Algiers, Tunis, and Tripoli.
