Torre Agbar

Joining La Sagrada Familia and the twin towers on the Port Olimpic, Torre Agbar has become synonymous with the Barcelona skyline ever since it was inaugurated with by King Carlos in 2005. A vast phallic shape exploding upwards in the resurgent district of Poblenou, the tower - according to its French architect Jean Nouvel - reminds us of a geyser; and it's certainly an appropriate image for what is the headquarters of the Aigues de Barcelona water company (Ag + Bar = Agbar!). A bona fide architectural masterpiece, Torre Agbar not only looks amazing with its 4,500 LED luminous devices which put on a light show for city residents every night, but the building also uses solar energy, non-toxic materials and even optimised elevator routes for maximum sustainability. Sadly, due to it being a place of work, visitors are not invited to climb Torre Agbar for what we can only imagine would be amazing views (you can try applying for a job with the water company!), but exhibitions do take place on the ground floor.

Shame you can't go in but still cool to admire from the outside. DEf. one of the Barcelona's most iconic buildings. We took a bike tour with Steel Donkeys alternative tours that led us there and was worth the visit

it looks very grey by day but super cool by night. GO to take night photos

What a great building. Much more beautiful than the Gherkin in London... it's slimmer and better proportioned and more colourful. I think I even prefer Torre Agbar to Gaudi!
