Venice IS a museum. The entire city is UNESCO. But inside the museum-city, specific museums contain art that would justify a trip even if the canals didn't exist. Palazzo Ducale's secret itineraries take you through torture chambers and Casanova's prison cell. Peggy Guggenheim's palazzo on the Grand Canal houses the most important modern art collection in Italy. The Gallerie dell'Accademia contains every Venetian master from Bellini to Tintoretto. And every 2 years, the Biennale turns the entire city into a global contemporary art laboratory.
1. Palazzo Ducale (Doge's Palace) (Piazza San Marco, €25 combo with Museo Correr). The seat of Venetian power for 700 years. Book the "Itinerari Segreti" (Secret Itineraries) guided tour (€28, 75 min — the torture chambers, the lead prison cells where Casanova was held, the rooms above the Great Council Hall ceiling). The main palace: Tintoretto's Paradise (largest oil painting in the world, 22m × 9m), the Scala d'Oro (Golden Staircase), the Bridge of Sighs (walk through it, connecting palace to prison). 2. Collezione Peggy Guggenheim (Palazzo Venier dei Leoni, Dorsoduro, €16). Peggy Guggenheim lived here 1948-1979. Picasso, Dalí, Pollock, Kandinsky, Ernst (her ex-husband), Magritte — in a palazzo garden on the Grand Canal. The most beautifully situated modern art museum in the world.
3. Gallerie dell'Accademia (Campo della Carità, Dorsoduro, €12). THE Venetian painting collection — Bellini's San Giobbe Altarpiece, Giorgione's Tempest, Titian's Pietà, Veronese's Feast in the House of Levi, Carpaccio's St. Ursula cycle. If you see one painting museum in Venice: this one. 4. Palazzo Grassi + Punta della Dogana (€18 combo). François Pinault's contemporary art collection in 2 stunning venues — Palazzo Grassi (Grand Canal, Tadao Ando renovation) + Punta della Dogana (the triangular customs house at the tip of Dorsoduro). The most important contemporary art collection in Europe after Tate Modern. 5. Museo del Vetro — Murano (€12 or combo ticket). Glass-making history from Roman to contemporary. Live demonstrations. See glass-blowing for free at independent fornaci (workshops) on Murano before buying — avoid the "free boat" factory tours.
