About
Claustra Alpium Iuliarum is a Late Roman barrier system, which guarded the crossings to Italy between the 3rd and 5th centuries. Ajdovski zid (“Ajdovski wall”) above Vrhnika is the longest known section of the Late Roman claustra Alpium Iuliarum barrier system. It measures over 6,700 m in length and has at least 35 barrier towers. The ancient Vrhnika (Nauportus) was enclosed underneath it.
