Villa Magna is the ancient name of a large imperial Roman villa near the modern town of Anagni, in Lazio, central Italy. The site lies in the Valle del Sacco some 65 km south of Rome, at the foot of the Monti Lepini, directly under the peak known as Monte Giuliano. The toponym 'Villamagna' remains attached to the site, attesting to the local memory of the imperial villa and its successive occupation as a monastery and lay community.
