TORRE DE AGBAR

Although it was only inaugurated in 2005, the Agbar Tower has become one of Barcelona's most important and emblematic skyscrapers. At 145 m high, it is the city's third tallest building.

It is the gateway to the city's technological district, known as 22@. The best time to visit is at night, when the building's coloured lights are switched on, lighting up the Catalan night sky.
