蒙特卡西諾-蒙特卡西諾大街

Monte Cassino (today usually spelled Montecassino) is a rocky hill about 130 kilometres (81 mi) southeast of Rome, in the Latin Valley, Italy, 2 kilometres (1.2 mi) to the west of the town of Cassino and 520 m (1,706.04 ft) altitude. Site of the Roman town of Casinum, it is best known for its abbey, the first house of the Benedictine Order, having been established by Benedict of Nursia himself around 529.

Casinum was an ancient town of Italy, probably of Volscian origin. Varro states that the name was Sabine, and meant forum vetus, and also that the town itself was Samnite, but he is probably wrong. When it came under Roman supremacy is not known, but it probably received the citizenship in 188 BC. It was the most southeasterly town in Latium adiectum, situated on the Via Latina about 40 miles north-west of Capua.
