The Franja Partisan Hospital

Franja Partisan Hospital is a unique monument of humanity, companionship, and solidarity from the Second World War. It operated as an illegal hospital in the difficult-to-access Pasica gorge in Dolenji Novaki near Cerkno between December 1943 and May 1945. It was led most of the time by Dr Franja Bojc Bidovec whom the hospital was named after during the war. Besides the staff, the locals also contributed to the successful operation of the hospital as they helped in building the huts, hiding the wounded in their homes and collecting food, medicines and other materials for them. Since the war, Franja Hospital has become a symbol of the Slovenian partisan healthcare and care of the wounded, helpless and those in need.  Franja is all this and much more – since 2015 a holder of the European Heritage Label!
