San Felice Circeo
Circeius Mons (mod. Monte Circeo) is an isolated promontory on the southwest coast of Italy, about 80 miles south/southeast of Rome, near San Felice Circeo, in the littoral between Anzio and Terracina; it is a part of Circeo National Park. It is a ridge of limestone about 3 miles long by 1 mile wide at the base, running from east to west and surrounded by the sea on all sides except the north. The land to the north of it is 53 feet above sea level, while the summit of the promontory is 1775 ft. Mount Circeo is today a protected park (see ) instituted in 1934 on 8,5 km² over the territories of Latina, Sabaudia, San Felice Circeo and Zannone Island (minor island of Ponza).
