Begun under Napoleon as the city's first green space, a large portion of these leafy public gardens serve as the main home of the Biennale, with curators and curiosity-seekers swarming the pavilions, from Carlo Scarpa's daring 1954 raw-concrete-and-glass Venezuelan Pavilion to Denton Corker Marshall's 2015 Australian Pavilion in black Zimbabwean granite. Part of the gardens is open to the public all year round; sometimes during off years you can wander among the pavilions and admire the facades.
