Belem Cultural Centre was built to host Portugal’s first presidency of the EU. It was designed by Vittorio Gregoti and Manuel Salgado with interiors by Daciano da Costa. The building closes a square/park in front of Jeronimos monastery. Nowadays it hosts the Berardo Collection, one of the world more relevant contemporary art collection, a conference centre, two theatres and several galleries and shops.
It looks like a cliff with brown stones maniacal of the same size. The pattern of the stones and the orthogonal structure of patios an inner squares makes a perfect machine to teach perspective. So I go there every semester with my students.
