A trip to Paris this summer included a visit to the Pompidou Centre. An exhibition on post-war Italian architecture, "La Tendenza, 1965-1985" was well worth a look with lots of drawings, models and paintings, many by the brilliant Architect Aldo Rossi. The exhibition had a real focus on the process of design and the changing attitudes to architecture. A particular highlight was the original model and drawings for Rossi’s San Cataldo Cemetery.
