The Torre Agbar (Catalan pronunciation: [ˈtorə əgˈbar]) is a 38-storey tower located between Avinguda Diagonal and Carrer Badajoz, near Plaça de les Glòries Catalanes, which marks the gateway to the new technological district of Barcelona, Spain. It was designed by French architect Jean Nouvel in association with the Spanish firm B720 Arquitectos and built by Grupo ACS.[4] The Torre Agbar is located in the Poblenou neighborhood of Barcelona and is named after its owners, the Agbar Group, a holding company whose interests include the Barcelona water company Aigües de Barcelona.[5]

The tower measures a total of 50,693 square metres, of which 30,000 are offices, 3,210 technical facilities, 8,132 services, including an auditorium, and 9,132 square metres for parking.

It opened in June 2005 and was officially opened by the King of Spain on 16 September 2005 and at a cost of 130 million euro.

The building is owned by the multinational group Agbar which has its corporate headquarters in the building and that takes up most of the floors, renting the remainder. The Agbar Tower was acquired in March 2010 for 165 million euro, after reaching an agreement with its former owner, the investment group Azurelau. Azurelau previously had bought the property in mid-2007. The purchase price was not disclosed.
