Asinara is the second largest island of Sardinia after Sant'Antioco. It is a narrow territory stretching from North to South, with a very indented coastline, which highlights the great variety of habitats. The island has an extremely peculiar historical, environmental, and juridical situation. Although the first evidences of human presence date back to the Neolithic Age, the environmental features of the area have been preserved thanks to a series of events which gave it the name of "Isola del Diavolo" ("Devil's Island").
