The Tower Agbar rises from the ground of Barcelona with power and lightness of a Geyser touching the bleusky. According to Jean Nouvel, The hill of Montserrat inspired the french architect in conceiving the Tower of Agua de Barcelona, the water company. Tall of 144 meters, this modern building hosts 30 000 m2 offices above-ground and an auditorium. On the facade 4550 LED luminous devices illuminates Barcelona nights. Jean Nouvel also brought a concept of sustainalbility by using a bioclimatic architecture adapted to the environment. Sensitive of its impact on nature and minimising environmental contamination, he took advantage of the surrounding climate and conditions. Today Agbar tower became like Sagrada Familia, Arts Hotel or Mapfre tower, a symbol of town sky conquest for a more exciting Barcelona Futur architecture. From far away or with a closer look, Architecture fans will be enchanted by this building.
