World Fairs have set miletones in architecture. The Crystal Palace (London 1851), the Eiffel Tower (Paris 1889) and the amazing buildings of the recent Expo Hannover 2000 are some examples.
This year, the Expo Zaragoza in Spain (June 14th – Sept 14th) features an astonishing pavillion/bridge by Zaha Hadid, and buildings by spanish architects Nieto y Sobejano, Francisco Mangado and Basilio Tobías. Below, pictures sent by spanish photographer Pedro Pegenaute.

Bridge Pavillion
This pavillion doubles as a pedestrian bridge over the Ebro river. Its structured by 4 “pods” that serve as exhibitio spaces. By Zaha Hadid and Arup.
Expo Building
Designed by Basilio Tobias. The skin of the tower makes it look like a giant lamp, a landmark for the expo
Spanish Pavillion
Designed by Francisco Mangado. The columns are made out of clay.
Congress Building
By Nieto & Sobejano Arquitectos, I love the section of this building.



























I am likely to be in Spain in Oct and would like to visit the Expo complex.Does anyone know if the expo buildings will be open for visits after the expo is over?
My sister the architect on the Spanish Pavilion, and says that the buildings are going to be converted into an office park after the expo. So you should still be able to see them.
The showcase is very interesting, it’s only missing the Digital Water Pavilion at the entrance of the Expo.
