Acquired by the Fondazione di Venezia in 2000, this fanciful neo-Gothic house was once the home of early-20th-century artist and photographer Mario de Maria, who conceived its distinctive brick facade with its three arched windows (its namesake 'eyes') in 1910. Now it hosts his photographic archive and fantastic Italian and international exhibitions of contemporary art and photography. The views of San Marco and the Punta della Dogana alone are worth the visit.
