Minturno is a city and comune in southern Lazio, Italy, situated on the north west bank of the Garigliano (known in antiquity as the Liris).

The early town grew around the square fort with polygonal stone walls on the side of the river and on the contemporary via Appia as a military road.

Its low site was increasingly abandoned by the population in favour of that of the modern town of Minturno (known as Traetto or Traietto, from Latin Traiectum, until the 19th century), 140 metres (460 ft) above sea-level.

Subsequently, it was a Caetani possession, and later assigned by Charles VIII of France to his general Prospero Colonna.

The impressive Roman remains mainly date to the Hadrianic period (built over earlier buildings) and consist of the: Close to the mouth of the river, about 2 km distant, was the sacred grove of the Italic goddess Marica.

The suburb of Scauri, on the Gulf of Gaeta, may take its name from the Roman consul Marcus Aemilius Scaurus, who had a sumptuous villa here.
