Claustra Alpium Iuliarum

is a Late Roman barrier system, which guarded the crossings to Italy between the 3rd and 5th centuries. The stone walls, which were in some places positioned in several lines, were supplemented by towers, fortlets and forts. The mighty system stretched from today's Rijeka in Croatia to the Bača Ravine (Baška grapa) in Slovenia.
