Since 2023, the Carsiana landscape has been enriched by two new structures built by Vojko Ražem, a master craftsman specialised in the construction of dry stone walls and ‘hiške’. These artefacts, located at the base of the sinkhole, were built using ancient traditional techniques that exclude the use of binding materials. Thanks to the natural flattened shape of the stones, characteristic of many areas of the Karst, it is possible to build without the use of cement. The stones are not even moulded, but skilfully arranged: each corner is reinforced with a large regular stone, while stones along the sides, of decreasing size towards the top, create the structure. Finally, smaller stones fill the central part and the gaps between the larger ones. The ‘hiška’ is the traditional shelter used by shepherds to protect themselves during the hottest hours or bad weather, while the cattle remained in the pasture. Sometimes it also served as a tool shed. These structures were generally built of local stone, with the entrance facing south, the side most sheltered from the winds. Interestingly, they were often small, which might suggest that the activity of shepherding was mainly carried out by children.

Dry stone walls, the art of whose construction was recently included in the UNESCO list of intangible assets, are a distinctive component of the Karst landscape. In addition to marking property boundaries and utilising stones removed during tilling, these walls offer an ideal habitat for local reptiles, providing perfect surfaces for ‘basking’ (warming in the sun).
