Grotta Lazzaro Jerko / Jama Lazar Jerko

Slipping into the earth’s embrace, we find Grotta Lazzaro Jerko. This cave, also known as Jama Lazar Jerko, whispers secrets of the karst landscape. Grotta Lazzaro Jerko sits at an elevation of 308 meters. It’s located in Italy, nestled 2 km southeast of Repen. It’s also 3 km north-northeast of Opicina and 4 km northwest of Monte Franco. The entrance to Grotta Lazzaro Jerko lies on the southern edge of a small valley. This valley is located between the valley of Grotta Meravigliosa di Lazzaro Jerko and the railway. The area around Grotta Lazzaro Jerko is partially wooded. Scattered boulders dot the landscape, adding to the rugged charm. A short shaft descends into the earth. A rock bridge narrows the entrance, adding a touch of drama. The shaft opens into a cavern oriented roughly north-south. The southern end closes off. To the north, a narrow, inclined passage leads to three distinct branches. One branch, heading northwest, is a short tunnel ending in a clay plug. Another branch, to the north, consists of an upward-sloping passage. It leads to a initially very narrow shaft that terminates in a small, decorated chamber. The third branch opens on the east wall of the cavern. It comprises a series of shafts, some filled with debris, others adorned with formations. These shafts lead to the cave’s deepest point. Here, a landslide blocks further exploration. Grotta Lazzaro Jerko remains a hidden gem, inviting us to explore its mysteries.
