Festival of water

The article highlights the Digital Water Pavilion of Expo 2008 in the Spanish city of Zaragoza. Created by architect Carlo Ratti it featured walls and roof made of water, and offered striking views over the Expo site and the Ebro River. International heavy-hitters Amp provided structural and mechanical engineering for the structure the first ever building with an external fagade formed from 'water curtains' digitally controlled to create openings allowing visitors to move freely in and out. Branded "an expo with no expiry date", it ran parallel with the so-called 'Water Tribune' a collection of conferences uniting the world's leading experts in water supplies and sustainable development.
