Dear Enric,
"Such is the German Pavilion: the architecture of reflections.
walls, paving stones and roofs form a prodigious blending
of rays of lights which criss-cross freely."(Marsa, Marsillach)
"The greatness of this art cannot be expressed materially.
Rather, it acts in ways which affect us even more profoundly"
(Peter Behrens)
Best.
