After passing from the Gonzaga domination to Venice, then back to the Gonzaga and again to Venice, the castle passed to the Austrian Empire and finally to private hands. The military base was demolished and the internal and external surface was transformed into agricultural land. In 1912 the castle was declared a national monument; it was bought by Senator Ugo da Como in 1920 who partly restored it, and since 1996 it houses the Museo Civico Ornitologico, conferences, weddings and theatral shows.
