Claustra Alpium Iuliarum:a Research Plan
After the golden age of the Roman Empire, from Augustus to Marcus Aurelius, known as the Pax Augusta, a time of insecurity starts, in which the Empire must be defended on all fronts. There are frequent barbarian raids on the territory of Illyricum and Italy, and defensive measures are being taken. One of these is Claustra Alpium Iuliarum, a system of defensive walls (barriers), forts and towers in the current Republic of Slovenia and the Republic of Croatia, designed as early as the time of the emperor Gallienus. It lasted until the emperor Theodosius 400 A.D. Claustra ought to be systematically researched with new technologies available (LiDAR, GIS and georadar), archaeological excavation should be performed, and Claustra should be presented to scientific and general audience and included in the List of UNESCO World Heritage.
