The Casa Rotonda (Round House), today home to the Donetta Archive, is located in Corzoneso. Between 1901 and 1932 it was the home of the photographer Roberto Donetta, who spent part of his life immortalising scenes of everyday life in the Blenio Valley. Today, the building is managed by the Donetta Foundation and its purpose is to preserve and promote Roberto Donetta’s “legacy” and to organise cultural events focusing on photography.

The Casa Rotonda is open every Saturday and Sunday from 2 p.m. to 5 p.m. and holds regular exhibitions.
