Agbar Tower

Like Gaudí at the Sagrada Familia, French architect Jean Nouvel was inspired by the rocky peaks of Montserrat when he imagined this multicolour rocketship aimed at infinity. Reaching a height of 142 metres – the third-highest building in the city – it has quickly become one of the iconic features of Barcelona’s skyline. There are 4,500 windows (count them), spread over its 38 storeys, and the entire façade turns into a spectacular lightshow at night, thanks to a vast array LED luminous devices.
