Vivara is a satellite islet of Procida , one of the three main islands in the Gulf of Naples . ( The other two are Ischia and Capri . ) Vivara flanks Procida to the south-west and is connected to it by a bridge . Vivara is a crescent-shaped remnant ridge of an ancient volcanic crater , part of the Phlegraean Fields . It is now a nature reserve of , established under D.M. 24.06.02 . In 1905 , Giuseppe De Lorenzo described it thus : Recent archaeological digs have uncovered fragments of Mycenaean/Late Helladic pottery together with Proto-Apennine and Apennine material , pointing to a Middle Bronze Age trading site ( emporium ) . Surveys around the coast , have established sunken coastal installations , pointing to extensive fishing and trading facilities , now up to 18m below the waterline . It is assumed that the lowest of these installations predate the Avellino eruption of Vesuvius , while some of the later ones may be associated with the Late Helladic material found elsewhere around the island
