The isle of Procida borders on the west on the islet of Vivara, joined to the rest of the island by a bridge built in the 1974, when an agreement with the owners let it be used for a while by the public (today it is closed). The islet has a semicircular shape, since it is a remainder of a volcanic crater and had hosted a Mycenean settlement of the 14th century b.C. Its name is probably derived from the medieval Latin "vivarium" (nursery) because the islet was used (other than for agricultural purposes) for the breeding of ground game. It fulfilled this function also during the 18th and 19th century, when the Bourbon kings chose the isle of Procida as their own game preserve. Nowadays Vivara is a natural reserve and inside the farmhouse that is on its top, belonging to the 17th century, there is a Naturalistic Centre.
