Portuguese architect Álvaro Siza's Grand Tour took him not to the Roman and Greek relics of the continent of Europe, but to the Incan relics of South America. In 1995, he took a sketchbook, clothes, and a poetry book to observe Macchu Picchu. Siza's sketches are on display at the Canadian Centre for Architecture as part of Alturas de Macchu Picchu (the name taken from Chilean Pablo Neruda's Canto General)—but with a twist. Siza's work is lined up next to the work of Peruvian photographer Martin Chambí, shown. Chambí beat Siza to the 15th-to-16th-century palace complex by about 50 years. The pairing is yet another way that architects can feed their nostalgia for sketching and how it translates to practice. Siza's 1977 housing development in Portugal serves as a case study. cca.qc.ca • Through April 29.
