A pleasant journey back in time: "Mostra Miniera del Resartico" (Resiutta Mining Exhibition). In 1844, Carinthian entrepreneurs began producing beer in Resiutta, which was then part of the Habsburg Monarchy, using the excellent water of the Resia River. A tunnel was dug for this purpose, which served as a storage and cooling room for the beer. By 1900, the resources of the icehouse were no longer used, and the icehouse remained empty. In recent years, the tunnel was rediscovered. Restoration and research work now allow visitors to retrace the course of history and visit this special place. The tunnel itself features information panels that illustrate the history of this place and beer brewing in Resiutta.

https://www.komoot.com/it-it/tour/692389420 The route follows CAI trail marker 720. Starting from the southern entrance of Rivellino Park, you cross it to the northern entrance. Crossing the park, you can already see the summit of Osoppo Hill with the flag flying on the lookout. The climb to the hill begins here, on the northern slope, and at the top of the trail, take the paved road on the left that leads to the fort. After passing the gate, on the right, there is a wide view of the Tagliamento River. On Osoppo Hill, there are many ruins worth visiting, given the strategic importance of the site since Celtic times. These include the roofless church of San Pietro, protected by a semi-cylindrical metal roof, the Savoy powder magazines, the tombs of the Savorgnans, the foundations of a Napoleonic barracks, and even the fossilized footprints of a Hipparion, the ancestor of the horse. The visit continues to the southern edge of the hill, to the Piazzale delle Cupole, where the remains of the artillery batteries are located, which can also be visited inside (a flashlight is recommended). A small path leads to the southern terrace, where the view opens up. Retracing our steps, we reach the square in front of the fort, with a small lake and the Casa del Tamburo (Drum House). On the right, there's another expansive view, this time towards Gemona. From this side of the fortress, we reach the lookout, where the Italian flag flies, the highest point on the hill, offering a 360-degree panorama. To descend from the hill, we retrace our steps and, after recrossing the gate, we leave the comfortable paved road to return to the left, taking trail 720 that descends towards the village. Once we reach the level ground, we keep right to head towards Parco delle Colonie. Here, we haven't found any sign of the trail marker, but by keeping to the south side of the soccer field and easily crossing a two-meter embankment, we reach the dirt road that leads to Colle di S. Rocco. After a right bend, on the left is the access to the steps leading up to the Colle. At a viewpoint overlooking the Tagliamento River, we also find the CAI notebook to sign our visit. Following the trail, keeping right at the first fork and then left at a second, we follow the entire crest of the Colle to the little church of San Rocco, opposite which lies the final few meters of descent. Once we reach the flat again, we keep left to return, through the village, to the starting point. 13-06-2020
