Held since 1895, the International Art Exhibition at the Venice Biennale attracts thousands to the romantic city. With works chosen by rigorous selection, it always features some of the best international artists at the Giardini di Castello and the Arsenale.

The Gardens are dotted with grand pavilions, each of which houses a nation's collection - the very best art that's been produced in the past two years. 

The Biennale has spread its tentacles all through this most picturesque of cities, and you'll need two or three days to see everything. Take a water-taxi to the crumbling Palazzo Papadopoli or wander the grounds of the cavernous Renaissance dockyard, Arsenale, which is home to many of the smaller nations' shows.

Curated by Bice Curiger, the 2011 edition takes a closer look at the relationship between contemporary art, artists and the public.
