The Water Tower (Spanish: Torre del Agua) is a 76-metre-high tower built at the Expo 2008 site in Zaragoza, Spain. It was designed by Enrique de Teresa and constructed of concrete, steel and glass.
It consists of a transparent structure erected in a droplet-of-water shape over a big three-storey basement. It provides 10,400 accessible square metres, 3,300 square metres in the basement’s floor and the remainder divided between the ramps and flat lands inside the glass tower. There is a 720 m² panoramic bar in the uppermost floor with views over the exposition site and the city.
During Expo 2008, the building hosted the Water for Life exposition.
