The Tower of Calanca (Corsican: Turra di a Calanca) is a Genoese tower located in the commune of Olmeto on the west coast of Corsica.
The tower was built in the second half of the 16th century. It 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.[1]
