Torre Agbar is a high-tech tower in the Poblenou neighbourhood of Barcelona, Spain. The 142 m tower was designed by Jean Nouvel and completed in 2005 at a cost of €130 million.
The bullet-shaped tower was designed to give the impression of land emerging out of the ground. Nouvel said of his design: "Unlike slender spires and bell towers that typically pierce the horizons of horizontal cities, this tower is a fluid mass that bursts through the ground like a geyser under permanent, calculated pressure."
The tower is made up of two concentric concrete oval cylinders topped by a dome of glass and steel. It is covered with a façade of aluminium and glass in the form of 60,000 coloured strips. The inclinations and opacities of the glass provide the tower with numerous alterations of colour and tone.
