Built in the early 20th century, the CAMUC - Casa Museo Cannas consists of a series of buildings that include, in addition to the main building, a set of small structures arranged around an internal courtyard, making it the most complex and imposing architectural complex in Ulassai. The building housed various commercial activities, managed by the owner's family, Massimo Cannas, as well as the post office. The two upper floors were used as the owner's residence, while in the basement there was a modern oil mill, an electric grain mill, and a coal-fired power plant built in 1924 that allowed the town, the first in the area, to have public and private lighting, and operated until 1934. Purchased by the Municipality of Ulassai around the mid-1990s, today, after a careful intervention of recovery and museum redevelopment by the architecture firm laiBE and engineer Paolo Depau, it is a versatile cultural center that hosts exhibitions, conferences, workshops, laboratories, and screenings.
