Carved into a vertical rockface in the Monte Cristallo massif, in Italy’s Dolomites Mountains, this incredible shelter sits at 2,700 meters (8,858 feet) above sea level.
Mountain climbers brave enough to take on the Via Ferrata Ivano Dibona in the Italian Dolomites are treated to many memorable sights, including that of a unique structure embedded in the side of a vertical rockface. The iconic location, known as Buffa di Perrero, is believed to be a shelter built by Italian soldiers during World War I. It features brick walls, a slanted roof, two doorways, and four windows framed in wood. It’s hard to believe, but someone had to carry all those building materials up the side of the mountain, as there is no backdoor to an easier access route.
