ecclesiastical structure of great value is the former convent of the Capuchin Friars of Masullas, in Sardinia. Built in the XVII century, in those same years was used as a lazaretto in occasion of the strong plague epidemic. Today the building houses the GeoMuseo MonteArci.
Inside the cloister there is a tank of cylindrical shape, with a capacity of nearly 300,000 liters of water, used in the past as a vital resource for the country, in periods of great drought. Today the structure is used as a museum of minerals.
The cloister, reachable from the outside after a few meters, is flanked by a good part from a short corridor covered that on the left directs toward the library and on the right toward small compartments with a staircase that leads to the upper floor. The monastery, also known as "Conventino", is composed of a single nave and some chapels on the right side.
