Venice still is a world capital of modern and contemporary art.
The Guggenheim collection is permanently residing in the city since 1980.
While alternating every two years the city hosts the Art and Architectural Biennale.
And every year both Palazzo Grassi and the Dogana open doors to the exhibits organized by the Pinault Foundation.
Last to join the contemporary art scene in Venice is the Prada Foundation now housed in the imposing Palazzo Corner.
