The Pontine Islands (/ˈpɒntaɪn/, also US: /ˈpɒntiːn/; Italian: Isole Ponziane [ˈiːzole ponˈtsjaːne]) are an archipelago in the Tyrrhenian Sea off the coast of Lazio region, Italy.
The other islands in the archipelago are Palmarola, Zannone, and Gavi to the northwest and Ventotene and Santo Stefano to the southeast.
According to a local legend, this was once the lost Kingdom of Tyrrhenia which sank with a narrow strip connected to mainland Italy.
Ventotene and Santo Stefano are land and sea conservation areas supervised by the Italian State.
Currently, tiny vineyards, wild herbs and flowers, and secluded beaches and grottos make them a popular tourist destination.
