Expo 2008
Zaragoza, the city of the international exposition, is the administrative and financial capital of the autonomous community of Aragon and Spain's fifth most populous city. It was elected the host city of Expo 2008 on 16 December 2004 by the BIE, beating Thessaloniki (Greece) and Trieste (Italy).
The exhibition's most emblematic buildings were the Torre del Agua, an high transparent building designed by Enrique de Teresa to evoke a drop of water, the Bridge Pavilion designed by Zaha Hadid, and the river aquarium. The exposition site also hosted several events, including a daily parade by Cirque du Soleil called ''The Awakening of the Serpent''.
Aside from the countries, non-government organizations and private companies took part in Expo 2008, always with the idea of water and sustainable development. Prior to the event, the Expo 2008 host committee estimated that the exposition could generate €135 million in tickets for admission to the exhibition center. Provided by Wikipedia
