Last year I was in Valencia to visit a conference. During the conference I also had some time to visit the well known "Calatrava buildings". These buildings do not only provide stunning views, when viewed in their full glory. They also contain several interesting details.
This photo was taken at the "tail of the "El Palau de les Arts Reina Sofía". I positioned myself under the tail, to then point my camera up to take this photo. The cloudless blue sky provided a nice, neutral, background.
