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.
