The Corbellini trail, built in the 1930s by carving into the mountainside, was intended to create easier connections between Sappada and the Pesarina Valley. Starting from the trail, the knowledge of the area was deepened through walks, visits, discussions and debates with those who know and live in the mountains and the two valleys.

In the meadow, in front of Cima Sappada's Ethnographic Museum, it was built the full-scale abstract model of the design proposal: the construction of two pavilions, one for each valley, along the trails. Two "gates" each consisting of a pair of rooms, whose shape recalls the slope of the roofs and the cross-section of the valleys, while the walls are made up of panels composed of elements of traditional architecture and decoration: wooden shingles, holes in the parapets, hay drying structures.

The "room" with the most open shape is dedicated to Sappada, the one with the sharpest shape to Val Pesarina: their conjunction represents the symbolic connection between places and communities, and an invitation to meet, exchange and share.
