La Via Latina, a road that was strategically advantageous in the military history of Rome, leads to the Algidus Mons mountain pass. Dionysius of Halicarnassus claimed that a town was founded on the mountain (Dion. Halic. x. 21, xi. 3), but this has not been verified by modern scholarship. Although an extensive fortification lines the Maschio d'Ariano (the hill to the south of the Via Latina), this particular structure was entirely medieval, and therefore did not exist during the time period described by Dionysius. However, some historical topographers have mistakenly included it on maps meant to illustrate Italy during the Western Roman Empire.
