Very special ruin, built like a swallow's nest on the rock - the short detour from the wide path onto a narrow, well-secured path is very worthwhile.

Kropfenstein/Casti Grotta, Waltensburg. It is a grotto castle that is difficult to access in a south-facing location. Access is from the east via a narrow ledge around a ledge. Today it is widened and secured by railings, but would leave the bike up there.

Kropfenstein/Casti Grotta, Waltensburg. It is a grotto castle that is difficult to access in a south-facing location. Access is from the east via a narrow ledge around a ledge. Today it is widened and secured by railings, but would leave the bike up there. The beam bearings of the former entrance are still recognizable. The castle is an elongated building wing, most of which is located under an overhanging rock screen

Narrow path, I would leave the bike at the top of the road for a moment, as the route is not very suitable for bikes.

The small path down to the castle ruins doesn't do much with the bike, I would definitely leave the bike up on the gravel road and walk the two or three minutes.

Worth seeing facility, about 700 years old. There is no direct documentary evidence of the castle or its builders. Kropfenstein, however, is one of the few grotto castles that were not built in a dark hole as a refuge in times of need, but served as a residence for a respected family, which among other things provided bailiffs and magistrates. Possibly the von Kropfenstein family of lower nobility based in Luven (Maschieras) built or acquired the Kropfenstein Castle or named themselves after it, while a branch of this family continued to reside in Luven. On November 28 or 29, 1328, during a procession in Rueun, a Jocobus de Strotznstein was killed. Whether this was an early owner of Kropfenstein or an as yet unidentified Stotznstein Castle in the Waltensburg area is uncertain. A Bürklin von Cropfenstein is mentioned in 1335, who worked several times as a judge, and in 1396 Albrecht von Kropfenstein, episcopal judge in Ilanz. His name will be mentioned several times in the years to come. 1401 Florin von Kropfenstein is mentioned. In 1433 Clara von Kropfenstein sold some goods to a donate from Kadunau. In the same year and again in 1437 Junker Hans von Kropfenstein is mentioned, who was nicknamed "Muschieras", which in turn indicates a connection to Luven. Close relationships with the barons of Rhäzüns can be proven. A feuding letter from Ulrich von Rhäzüns and Hans von Kropfenstein to the castellan of Freudenberg has been preserved from May 3, 1437. The best-known Kropfensteiner was Marquart von Kropfenstein, who was a judge of the Gray League in 1438/39 and 1442/43. Junker Jörg von Kropfenstein is mentioned in 1473, who at that time attached his seal to a contract of sale from a Waltensburger. Towards the end of the 15th century, perhaps with Junker Jörg, the von Kropfenstein family must have died out and the castle began to crumble.
