The Torre del Cerrano Protected Marine Area was established by a Decree of the Italian Ministry of the Environment and Protection of Land and Sea dated 21-10-2009, published in the Official Journal of the Italian Republic No. 80 of 07-04-2010.
It extends up to 3 nautical miles offshore and stretches for 7 km, 2.5 km of which are sandy dunes along the shore, from the mouth of the Calvano creek, which crosses the town of Pineto, to the centre of Silvi, at the railway station. The Protected Marine Area covers a surface of 37 sq.km and includes a small zone B of approximately one km in front of Torre Cerrano, a zone C of 14 sq.km, which extends along the entire sea front to about 2 km from the coast, and a large zone D of approximately 22 sq. km near the limit of three miles.
The body of water of the Torre del Cerrano Protected Marine Area features two closely related environmental settings. On the one hand, the typical sandy seabed of the Adriatic, which characterises the largest portion of the area. On the other, hard substrates formed by the half-submerged rocks of the ancient port of Atri, the submerged structures of the provincial marine nature reserve, and conglomeratic outcrops.
The area also features a large number of pelagic and benthic marine animals and a small yet significant contingent of plant species. In addition to the beautiful specimens of rare Adriatic gastropods, such as the Trivia Adriatica, and the large bioconstructions of Sabellaria halcocki. In the underwater environment of the protected area, you can spot many species of fish and molluscs, including congers, basses, soles, and white breams, which live in contact with the sandy seabed characterised by large clam beds (Chamelea gallina).
