The Fortezza Vecchia (literally “old fortress”) rises on a granite promontory near Capo Carbonara;overlooking the sea.It was built in 1580-1590;perhaps to fortify a pre-existing structure dating back to;the 14th century.It is part of a coastal defence system wanted by Philip II of Spain against Barbaresque raids.Garrisoned in 1590-91;it had an important role until 1847.Originally the fortress had a triangular shape.In 1790 it became quadrangular and small ramparts were added on the four corners;giving the fortress its characteristic star shape.
