Dry only in the stereotypes, Iran is rich in mountains and rivers and throughout its past history demonstrated an exceptional care for its hydric resources. That’s why it sounds odd the fact that today, due to a grid in bad conditions and a growing agriculture, Iran has turned into the main water wasting country in the world. The content of the pavilion is hence a vast photo reportage on the dams, the aqueducts and the subterranean channels of the glorious Persian past, put into comparison with the datas on the actual wastage. The setting, placed on the ground floor by the end of Fondamenta di Sant’Anna, consists in a cubic case sunken in the channel in front of the entrance and generating a void in the water, and another case of the same dimension, filled in water, in the interior. An essential transfiguration of all the artificial works designed by the mankind to irregiment water: Powerful gestures, necessary to the survival, sometimes extreme but almost always fascinating.
