Kleine Berlin is the biggest system of underground anti-aircraft tunnels still in existence in central Trieste. It consists of two distinct but interconnected systems, one built by the city authorities as a bomb shelter for the civilian population, and the other, which had a completely different structure and was used as a warehouse, storage depot and air raid shelter, built by the German army after the SS Adriatisches Küstenland (Adriatic Coast) headquarters were set up in Trieste on 8 September 1943. The Italian section is made up of a network of tunnels containing basic equipment for brief stopovers, a sick bay and restrooms.Visit Italy. Italy Epic Route © Monika Newbound
