National pavilions at the Venice Biennale
The national pavilions host each participating nation's official representation at the Venice Biennale, an international art biennial exhibition held in Venice, Italy. Some countries own pavilion buildings in the Giardini della Biennale, while others rent buildings throughout the city; however, each country controls its own selection process and production costs.
