The Venice giardini is an area of parkland in the historic city of Venice which hosts the Venice Biennale Art Festival, a major part of the city's cultural biennale. The gardens were created by Napoleon Bonaparte who drained an area of marshland in order to create a public garden on the banks of the Bacino di San Marco which is a narrow stretch of water dividing the gardens from St. Mark's Square and the Doge's Palace. The gardens contain 30 permanent pavilions. Each pavilion is allocated to a particular nation and displays works of art by its nationals during the Venice Biennale. Several of the pavilions were designed by leading architects of the 20th century, including Carlo Scarpa.
