The town's name derives from the personal name "Carolus". Municipality in the province of Udine, which includes the main centre and the district of San Gervasio, located in the Friuli plain, stretching out to the Laguna of Marano. The town is rich in history and features a total of 32 archaeological sites.
The discovery of prehistoric artifacts from the Neolithic to the Iron Ages and others of the Roman period, evidence that the area has been inhabited since very ancient times. In the II century B.C, the Imperial Romans troops conquered the area and forced the Celts to find shelter into Veneto. After the fall of the Roman Empire, the lands were inevitably exposed to the invasion of other populations and here, in 568, settled the Lombards, later defeated by the Franks. In 967 Emperor Otto I granted a large stretch of territory, including Carlino, to the Patriarchate of Aquileia. The town is mentioned for the first time in a document of 1031, while it was proclaimed municipality in the late Middle Ages. In the XIII century, the Venetians with the intention to expand the boundaries of their Republic, inevitably started a conflict with the Patriarchate, occupying the area permanently in 1420. In the XVI century, Carlino submitted the Austrian rule, followed by the Napoleonic period, until it was annexed to the Kingdom of Italy.
