There are two parts in Biennale; Giardini and Arsenale.
I could only go to Giardini because of my short stay in Venice.
I definitely enjoyed each country's pavilion more than the central exhibition. There is something very nice about the intimacy between each art and architecture.
These are some photos from Giardini pavilions..
