The Papal Archbasilica of St. John Lateran (Italian: Arcibasilica Papale di San Giovanni in Laterano), commonly known as St. John Lateran's Archbasilica, St. John Lateran's Basilica, and just The Lateran Basilica, is the cathedral church of the Diocese of Rome and the official ecclesiastical seat of the Bishop of Rome, who is the Pope.

The Catacomb(s) of Callixtus (also known as the Cemetery of Callixtus) was one of the Catacombs of Rome on the Appian Way, most notable for containing the Crypt of the Popes (Italian: Capella dei Papi), which contained the tombs of several popes from the 2nd to 4th centuries.

San Sebastiano fuori le mura (Saint Sebastian outside the walls), or San Sebastiano ad Catacumbas (Saint Sebastian at the Catacombs), is a basilica in Rome, central Italy. Up to the Great Jubilee of 2000, San Sebastiano was one of the Seven Pilgrim Churches of Rome, and many pilgrims still favor the traditional list.

The Alban Hills (Italian Colli Albani) are the site of a quiescent volcanic complex in Italy, located 20 km (12 mi) southeast of Rome and about 24 kilometres (15 mi) north of Anzio.
The dominant peak (but not the highest) is Monte Cavo at 950 m. There are two small calderas which contain lakes, Lago Albano and Lake Nemi. The rock of the hills is called Peperino (lapis albanus) a particular Tuff, a combination of ash and small rocks that is useful for construction, and provides a mineral-rich substrate for grape vines.

The first records of the area date back to the IX century in the Lombard period. The position of the town was strategic for enemies attacks during the Middle Age. Lately, the town became an important cultural and religious center. It was home for many Bishops until the 1973 when the Diocese of Campagna merged with the Archdiocese of Salerno.

The mountains lend their name to the Apennine peninsula that forms the major part of Italy.[5] They are mostly verdant, although one side of the highest peak, Corno Grande, is partially covered by Calderone glacier, the only glacier 

The Sabine Hills is an area just north of Rome in Lazio in Italy. Perhaps most famous because its population fell victim to the “Rape of the Sabine women” by Rome, the hills have some interesting small towns.
