In a village of the Emporda raises this icon in the landscape, a municipal water tank built-in 1962. We were asked to reconvert it and proposed a panoramic viewing point without losing the memory and image of the tank. By creating a spiral shape around its base don the experience of the views of its surroundings, we accomplished a game of absence and presence. Raping the new structure with a metallic mesh to obtain these results, during the day the tank is seen thru the mesh. When the night comes, the proposal is illuminated and the mesh disappears because of its high degree of transparency and the historic tank come to life.
