Ponza is one of the jewels of the Mediterranean, with beaches, jagged cliffs and crystal clear water, which attracts visitors from all over the world.
Of volcanic origin, the island has an area of 7.5 square kilometers. It is hilly, extending from Punta La Guardia to Punta Incenso. It is filled with Mediterranean vegetation of agaves, prickly pears and wild broom.

In its past, Ponza was dominated by the Volsci,  Phoenicians, Greeks, and by the Romans form 321 BC. The Romans built the Grotte di Pilato and the Cave dei Serpenti, an aqueduct which supplied water to the island, tankers, villas, and tunnels dug into the tuff.
The Patron's celebration is on June 20, Festa di S. Silverio.
