An integral part of the Argentario Ecomuseum, this body of water is located in a wooded basin at almost 1000 m above sea level, in the southern part of the Cembra Valley. Despite not having significant dimensions (it measures 310 m in length, 120 m in width, and a maximum depth of 8 metres) it represents an element of great landscape importance and a place of incredible naturalistic importance. The geological interest of the basin is given by its location on a fault that separates lava rocks (quartz porphyries) from sedimentary rocks (Calisio limestones). Its origin is very particular: the basin was certainly "worked" by glaciers, as is evident from the smoothing of the large rocks located on the north bank, today characterized by the presence of a dense reed thicket. Tufts of sedges grow almost everywhere, while its waters are surrounded by lush forests of Scots pine. In spring, the wonderful white-pink inflorescences of the fibrino clover emerge in the shallow water areas. Today the ichthyofauna guarantees a high level of fish in the lake, which has at least 10 confirmed species. Mallard ducks, coots and moorhens nest in the reed thicket in spring. But the faunal importance of the lake and the swamp is above all due to the amphibians, which come here in spring from the surrounding areas to mate and lay their eggs: as many as 6 species have been observed to date.

Today all that remains of Castelfeder is a few suggestive ruins. In the 13th century, however, it had been an important castle built by the lords of Enna. It stood on a hill between the current municipalities of Ora, Egna and Montagna. All around the castle ruins there is a larger area where there are remains of other buildings dating back to various eras. Everything is immersed in the so-called Castelfeder biotope, a protected natural area covering 108 hectares.

The Castelfeder hill is an ancient cultural landscape with traces of settlements from the Stone and Bronze Ages. The remains of a castle complex, the legendary fertility slide, bowl stones and the walls of the Barbara Chapel bear witness to a mystical past. The area is important from an archaeological, historical and ecological point of view. Years ago it was placed under landscape protection as a biotope.
