The eastern tip (punta) of Dorsoduro is crowned by the distinctive triangle of the 17th-century Dogana di Mare (customs house) that once monitored all boats entering the Grand Canal. Transformed by Tadao Ando into a beautiful exhibition space in 2009, it’s now an engaging showcase for the contemporary art collection of French multi-millionaire François Pinault (officially dubbed the Centro d’Arte Contemporanea Punta della Dogana). It’s pricey, but you can expect to see quality work from Cindy Sherman, Cy Twombly, Jeff Koons, and Marlene Dumas, among many others.
