City of Arts and Sciences. Born from the mind and pencil of Santiago Calatrava (born right in Valencia), this "city within a city" is famous worldwide as an example of avant-garde architecture, known as "organic". The five buildings that make it up perfectly match the surrounding environment: the clean lines, the white that contrasts with the blue and the reflection of light in the water of the pools. The most scenic is the Hemisféric, the large hemispherical structure that, reflected in the water, completes the circle recalling a human eye. Even if you are not an expert in science, art or architecture, it is a place not to be missed.
