#ArchMTL @MTLExchange @Montreal @heritagemtl Montreal Stock Exchange Tower, 1964 by Luigi Moretti, Pier Luigi Nervi The tower itself is a masterpiece of the International style of skyscraper design. Its façade features a bronze-tinted anodized aluminium curtain wall, forming a strong contrast with the slightly slanted pre-cast concrete columns at the four corners, giving the whole a subtly convex aspect. It is divided into three roughly equal blocks by mechanical floors whose corners are recessed in an octagonal shape, creating small open-air interstices behind the columns at these levels. One couple of peregrine falcons has been nesting inside the 32nd floor recess since 1984.
