The sites of the hillforts of Volam and Gradina, north of Premantura, Kastril and Debeljak have been inhabited since prehistory, while sites from Antiquity and Late Antiquity are located in Močila Cove, Polje, Sveti Martin, Kastril and Skokovica.
The goddess Minerva, the patron of wisdom and the arts, commerce, crafts, warfare and medicine, was one of the chief Roman deities. The bronze figurine was found on the shore in Premantura in 1930, dated to 1st or 2nd century. It probably belonged to a household shrine in a nearby Roman villa.
