Cave del Predil (historical name “Raibl”, Italianised with annexation after 1918) is located in the municipality of Tarvisio (UD), north of the Alpine watershed. Surrounded by mountains (Cinque Punte, Monte Re and Cima del Lago), the nearby Lake Raibl (or Lake Predil) with its small island (the legend of Christmas Eve is worth mentioning) offers an evocative landscape. The adjacent Predil Pass, visible from the lake, marks the border with Slovenia.

The origins of Cave are linked to mining (extraction of lead and zinc from Monte Re already in pre-Roman times), an activity that ceased in 1991. Today, the Mining Museum is located in the building that housed the management offices. Part of the most accessible tunnels have been secured and opened to the public in the Parco Internazionale Geominerario.

Two interesting facts about the mine: on 8 January 1910, the hospital was sucked into a sinkhole that opened immediately below, there was only one survivor, 7 people died, a column stands in memory of the tragedy. In 1917, the mine’s drainage gallery, which discharged underground water in Bretto (today Log Pod Mangartom in Slovenia) equipped with a small train, allowed the Austro-Hungarian army to transfer hundreds of thousands of soldiers and thousands of tons of war material without the knowledge of the Italian army, thus contributing to the famous breakthrough of Caporetto.
