San Gaudenzio is one of the great Late Gothic church buildings in Graubünden. It follows the classical style with a single nave and indented polygonal choir. The vaults have collapsed, but the outer walls have mostly survived. They showcase an extraordinary width and height of space, elegant lancet windows with filigree fillings (tracery) as well as precise stonework.

In 1925, the first stabilization work of the church ruins was carried out on the initiative of the Bregaglia artist Giovanni Giacometti, and under his direction. From 2009 onwards, the urgently-needed preservation and restoration work was sponsored by the San Gaudenzio Foundation in close cooperation with the historic monument preservation authorities and the Archaeological Service of the Canton of Graubünden.

From 2009 to 2022, extensive conservation and restoration work was carried out in two stages on the San Gaudenzio church and hospice ruins. The conservation and restoration work were made possible thanks to contributions from the Bregaglia municipality, the Maloja Region, the canton of Graubunden, as well as foundations and individuals.
