Gun Emplacement Tunnel of Monte Cengio

The emplacement was built between the spring and summer of 1917: the entire area (like many others in the Pre-Alps) was fortified following the Strafexpedition of 1916, to hinder any future Austro-Hungarian attacks.
The gallery is very wide and majestic: average width of 2 m, length of about 74 m, 4 caves/munitions depot.

I would like to point out that in the second part of the descent from Monte Tondo the path is very damaged. Therefore, once you reach San Donato, it is best to head towards the church and go down the route you have already taken uphill.

Bus de la Lum Sinkhole
Highlight • Cave
During the Second World War, the cesspool was used by partisans (the resistance was particularly active in the Cansiglio area) to dump the bodies of several soldiers of the Italian Social Republic and German soldiers, as well as civilians. Burial in natural caves has led some sources to compare this event to the Venezia Giulia (the Foibe) massacres.
According to the association Silentes Loquimur, created specifically to commemorate the victims of the Bus de La Lum, a 1949 report by the Carabinieri of Vittorio Veneto counted over 300 victims, while the speleologists of the Italian Cave Rescue Center were working on theirs Investigations in the 1960s assumed up to 500 victims (200 German soldiers, 100 RSI soldiers, 200 civilians). The same association reports that in the early 1950s the remains of 26 people were recovered, while a search carried out in 1992 turned up another 68 people who were later buried in the Caneva cemetery. No further surgeries have been performed since then due to the high economic cost.
According to Umberto Lorenzoni, president of the Treviso ANPI, "no more than a dozen skeletons were recovered" from the Bus de la Lum; and when, in the early 1990s, the president of the ANPI of Pordenone, Bruno Giust, asked for further investigations to be opened, "we were told by the president of the Victims' Association that it was not appropriate to proceed. Obviously because, in our opinion, there was nothing else to be found gave". He concluded that the Bus de La Lum was used as an improvised burial ground in the final months of the war, at a time "when nothing else could be made available".

Val Sorda Gorge and Waterfalls
Highlight (Segment) • Gorge
The tour is not easy. There are quite a few differences in altitude, you should be sure-footed and not afraid of heights and wear sturdy shoes. The tour is varied with a suspension bridge, cave, great water-filled gorge, super exciting guided tour, waterfalls, forest motifs like in paradise, but there are also mountain panoramas and pools that invite you to cool off. I wouldn't miss it 😉.

Tips from the Community
The Grotto of Santa Felicita is located in Teolo, on the southern slope of Monte della Madonna, within the Euganean Hills Regional Park. It is a place shrouded in mystery and spirituality, closely linked to the figure of the saint who, according to tradition, retired there as a hermit between the 8th and 9th centuries. The grotto is a natural cavity located right next to the small church of Sant'Antonio Abate. Inside, it holds one of the highest water springs in the hills, once considered miraculous. The site, surrounded by Mediterranean vegetation where the dwarf prickly pear grows spontaneously, emanates an atmosphere of absolute peace. Reachable by an easy walk, the grotto represents one of the most evocative stops for those exploring the trails of Teolo, combining the charm of volcanic geology with the popular devotion that still sees this cave as a symbol of rebirth and contemplation.

74 meter long tunnel with no exit and 4 final outlets where the artillery was positioned. A light was needed.

The name probably derives from "lume" or flame, due to the luminescence that would have been seen on summer nights above the cavity, produced by the gases generated by the putrefaction of animal carcasses thrown into the well. The cavity was formed by karst, or by the dissolution of the rock by water. According to legend, it is inhabited by the Anguane, very ugly fairies, with nails instead of hair, and long fangs instead of teeth. During the day they went to wash clothes at Lake Santa Croce, then wandered around in search of wood, food and children to roast. At night, they lit a small fire, whose light, spotted by shepherds, gives the cavity its name
