The Coastal Tower of Petacciato rises along the State Road that runs along the Adriatic Sea (SS 16), towards the side of the coast, at the same level of the road and at about 7 meters above sea level. Situated at the foot of the homonymous Marina di Petacciato, this tower is the last tower of a defensive system against the Turks, the twenty-fifth according to the numbering given by Gambacorta. It communicated to the north with the Trigno Tower, 6-8 km away and to the south with the Sinarca Tower, 6.5 km away. Wanted by Charles V in the XVI century, the tower is located in a privileged position and it is the result of precise strategic choices. In fact, all the towers had to have the view on all four sides and to be in visual connection with each other and with the villages behind.

The 'Trappeto Maratea' Museum is an extraordinary underground site of industrial archaeology in full activity since the Middle Ages in the heart of Vico del Gargano.
