The hospital was built in 1943 by Dr. Viktor Volčjak and Dr. Franja Bojc Bidovec, the latter of whom became the site's namesake.
To maintain total secrecy, all wounded patients were blindfolded before being transported to the hospital by stretcher bearers.
The hospital featured specialized cabins including an operating room, an X-ray room, and a surgical department.
The facility operated its own small-scale hydroelectric power plant to provide electricity to the surgical cabins.
The 2007 flood completely washed away the original cabins; the current structures are faithful reconstructions based on archived photographs and blueprints.
Patients were kept in strict anonymity; staff only referred to them by number to prevent accidental leaks if captured.
The hospital grounds included a dedicated cabin for the 'kitchen' and food storage to ensure self-sufficiency.
Despite being a military hospital, it strictly followed international medical humanitarian standards, treating wounded from both sides of the conflict.
The site remains one of the few surviving examples of a hidden partisan hospital network in occupied Europe.
The Franja Partisan Hospital is a secret World War II facility hidden within the narrow, rugged Pasica Gorge near Cerkno. Operated by the Slovenian Partisans between 1943 and 1945, the hospital served as a clandestine medical center for wounded soldiers of various nationalities. It comprises a complex of 14 wooden cabins designed to be invisible from the air, concealed by the gorge's dense forest and steep rock walls. The site was never discovered by German forces despite their proximity. Today, the hospital functions as a museum dedicated to humanitarian efforts during wartime. The original structures were largely destroyed by a catastrophic flood in 2007 but have since been meticulously reconstructed. Visitors traverse the gorge via a narrow path to reach the site. It is a symbol of resistance and international cooperation, as patients included Allied soldiers. The site holds the European Heritage Label for its significance in European history.

Wear sturdy, non-slip footwear as the trail through the gorge can be damp and rocky.
Bring a light jacket, as the temperatures inside the deep, shaded gorge are significantly lower than the surrounding Cerkno plateau.
Plan your visit for a dry day, as heavy rain can make the trail through the gorge hazardous.
Attempting the walk during or immediately after heavy rainfall due to risk of flooding and slippery paths.
The site is typically closed during the winter months due to safety risks from ice and snow in the gorge.
Maintain a quiet and respectful demeanor; this site is considered a memorial and a place of reflection.
