Rupnik Line Defence System and Flood Safety

At the Rapallo border in the Sovra Valley near Žiri, the dual role of the Kingdom of Yugoslavia’s defence infrastructure was recognised. It was found that the anti-tank walls had an additional function of flood control. The field survey included three previously unknown anti-tank walls that also crossed watercourses by cutting the direction of a possible invasion by the Kingdom of Italy. Understanding the defence strategy followed by the Kingdom of Yugoslavia in the construction of the defence system along the Rapallo border, one can assume that this dual function was planned.
