The 2008 World’s Fair is to begin in Saragossa, Spain, later this month.

Called Expo Zaragoza, the Spanish spelling of the city, the 93-day event will have the topic of 'Water and Sustainable Development' and is being coordinated by the Bureau of International Expositions.

Featuring buildings designed by Zaha Hadid (the Bridge Pavilion, which is expected to be turned into a museum after the event) and Enrique de Teresa (the transparent, 76m tall Water Tower), the expo will also boast the largest freshwater aquarium in Europe.

The aquarium will feature 300 species of fauna from different rivers around the world in more than 60 tanks or terrariums.

More than 100 countries are expected to participate in the expo, which is estimated to generate 135m euros (£106m) in admission fees alone.

Expo Zaragoza 2008 will run from 14 June to 14 September. Details: www.expozaragoza2008.es
