Jean Nouvel has once again left his iconic mark on the skyline of a city—this time with Barcelona’s Torre Agbar. The bullet-shaped silhouette takes its inspiration from the famous Catalan mountain, Montserrat, the crawling waves of the Mediterranean Sea, and of course throws a bit of Gaudi influence in the mix as well.

The lighting composition of the glass louvers creates an abstraction akin to the breaking of waves against a rock formation, and the colors are arranged in a fractious manner which alternate randomly between blues and reds. The exterior lighting is quite spectacular—4,500 multicolored LED panels beautifully illuminate the night every time the sun goes down. Torre Agbar is currently Barcelona’s most visible tourist attraction, and according to its designer, is ”one of (Barcelona’s) best ambassadors”.
