The Giardini della Biennale are the primary venue of the Venice Biennale and one of the few substantial green spaces in Venice's dense urban fabric. Located at the eastern edge of the Castello sestiere, the gardens were created in 1807 on the orders of Napoleon Bonaparte, who had the area cleared by demolishing several churches, monasteries, and a sailors' hospice. What replaced them was a public garden in the Napoleonic civic tradition: a rational landscape of tree-lined avenues, open lawns, and shaded walkways along the lagoon waterfront.

The gardens took on their current identity starting in 1907, when the first permanent national pavilions were built to house country-specific exhibitions for the Venice Biennale, which had been running since 1895 (Martini, 2020). Over the following century, 30 permanent pavilions were constructed, each designed by architects selected by the participating nations. The result is an open-air museum of 20th-century architectural styles, where every building reflects the cultural ambitions of its moment.

Several pavilions are architectural landmarks in their own right. The British Pavilion, dating to 1909, is a neoclassical structure that has been modified several times. The German Pavilion, also originally from 1909, was controversially rebuilt in 1938 in a monumental style during the Nazi period, a history that contemporary German artists have repeatedly confronted in their installations. The Nordic Pavilion, shared by Finland, Norway, and Sweden, was designed by Norwegian architect Sverre Fehn in 1962 and is widely regarded as a masterpiece of Scandinavian modernism: a luminous concrete-and-glass structure threaded through existing trees. More recent additions include pavilions by Australia, South Korea, and other nations, with the newest permanent structures dating to 2018.

At the heart of the Giardini stands the Central Pavilion (formerly the Italian Pavilion), which hosts the main curator-driven exhibition at each Biennale. This is typically where the artistic director presents their thematic vision for the edition, bringing together invited artists from around the world.

Between Biennale seasons, the Giardini function as a public park. Entry is free, and the pavilion exteriors can be admired from the pathways. The gardens offer shaded benches, lagoon views, a playground, and a welcome respite from the intensity of sightseeing in central Venice. During the Biennale (late April to late November in exhibition years), a full Biennale ticket is required to enter the pavilion area and view the exhibitions.

The Giardini are a 15-minute walk from the Riva degli Schiavoni waterfront promenade or a short vaporetto ride to the Giardini stop. They pair naturally with a visit to the nearby Arsenale, the Biennale's second major venue, which is a 10-minute walk east along the waterfront.
