Jean Nouvel’s 142 metre high Torre Agbar in Barcelona will be opened by King Juan Carlos today and will become the new headquarters for water company Aguas de Barcelona. Nouvel worked with local architect b720 on the project. The building’s envelope is formed of two non-concentric oval cylinders and said to be inspired by Gaudi and the hills of Monserrat. Nouvel expands, “The ambiguities of material and light make the Agbar tower resonate against Barcelona's skyline day and night, like a distant mirage, marking the entry into the diagonal avenue from the Plaça de les Glorias. This singular object will become the new symbol of Barcelona the international city, and become one of its best ambassadors.”
