Roman Castles in the context of "Frascati (wine)"

Castel Gandolfo (UK: /ˌkæstɛl ɡænˈdɒlfoʊ/, US: /kɑːˌstɛl ɡɑːnˈdoʊlfoʊ, -ˈdɔːl-/, Italian: [kaˈstɛl ɡanˈdɔlfo]; Latin: Castrum Gandulphi), colloquially known as Castello in the Castelli Romani dialects, is a town located 25 km (16 mi) southeast of Rome, in the Italian region of Lazio. Situated on a hilltop in the Alban Hills with panoramic views of Lake Albano, Castel Gandolfo is home to approximately 8,900 residents and is renowned as one of Italy's most scenic towns. It is one of I Borghi più belli d'Italia ("The most beautiful villages of Italy").

Within the town's boundaries lies the Apostolic Palace of Castel Gandolfo, which has served as the summer residence and vacation retreat for most popes since 1626. Although the palace is located within the borders of Castel Gandolfo, it holds extraterritorial status as one of the properties of the Holy See and is not under Italian jurisdiction. It has been transformed into a museum and is now open to the public. In spite of the main Apostolic Palace's current status as a museum, the Castel Gandolfo complex would have its traditional status as the pope's summer residence and vacation retreat restored in July 2025.

Rocca di Papa (Roman Castles Romanesco: 'A Rocca) is a small town and comune (municipality) in the Metropolitan City of Rome, Lazio, Italy. It is one of the Castelli Romani about 25 kilometres (16 mi) southeast of Rome on the Alban Hills. It is close to the other communes of Velletri, Rocca Priora, Monte Compatri, Grottaferrata, Albano and Marino. It is the center of the Regional Park known as the "Parco Regionale dei Castelli Romani".

Albano Laziale (Italian: [alˈbaːno latˈtsjaːle]), sometimes known simply as Albano (Romanesco: Arbano; Latin: Albanum), is a comune (municipality) in the Metropolitan City of Rome Capital, on the Alban Hills, in the Italian region of Lazio. Rome is 25 kilometres (16 mi) distant. It is bounded by other communes of Castel Gandolfo, Rocca di Papa, Ariccia and Ardea.

Partially included in the Roman Castles Regional Park, Albano is one of its most important municipalities, and a busy commercial centre. It has been also a suburbicarian bishopric since the 5th century, a historic principality of the Savelli family, and from 1699 to 1798 the inalienable possession of the Holy See.

Marino (Latin: Marinum or Castrimoenium, Marino dialect: Marini) is an Italian comune with 46,676 inhabitants located in the Metropolitan City of Rome Capital in Lazio.

Situated south of the capital, on the Alban Hills in the area of the Roman Castles, nestled between Rocca di Papa, Castel Gandolfo, and Grottaferrata, the town was a significant military outpost on the Ager Romanus throughout the Middle Ages, a popular vacation destination, and an important commercial hub due to its strategic position on the highway between Rome and Naples, which was frequented until the reopening of the faster Via Appia Nuova around 1780.
