The literal translation of "Via ferrata" in Italian is "The Iron Route". Basically it’s a system of ropes, tricks/holds, ladders and other elements that facilitate rock climbing. The first ever attraction of that type appeared mid- 19th century in the Alps - the Dachstein Massif. In World War I, they became very popular as they were used in hostilities between Italy and Austria in South Tyrol. One such rock route in Bulgaria is "Lednitsata" located near “Saeva hole” cave, the region of Lovech. The 30- meter deep karst hole is equipped with a variety of rock routes with varying degrees of difficulty. The routes were built close to the pits the “Small” and “Large Lednitsa”- in the past specific for them was that almost year-round they maintained freezing temperatures, hence the name given by the locals “The frosty place”. Many years ago they stored ice wrapped in straw, almost throughout the year.
