Venice packs centuries of art, faith, and spectacle into a maze of canals, so prioritizing is essential on a short visit. St. Mark's Basilica and the adjoining Doge's Palace anchor the Byzantine and Gothic heart of the city, both facing the sweeping St. Mark's Square where Venetian life has gathered for a thousand years. A short walk over the Rialto Bridge leads to the Gallerie dell'Accademia, home to the finest collection of Venetian painting anywhere. Time it right and you can also catch Festa del Redentore, the summer fireworks feast that locals still treat as the city's true celebration. Together these picks cover Venice's essential art, architecture, and living traditions in one manageable itinerary.
