In case you were wondering where the funny door on the first post comes from: it is one of the amazing details of Casa da Musica, the new auditorium of Porto.

Casa da Musica, by Dutch architects OMA, is just the newest gem in a panorama of oustanding architecture spanning from the Middle Age to the present times.
