Traces Left Behind illustrates the role Buffalo’s grain-silos played as strategic infrastructure, architectural icons and technology innovators in America’s industrial heritage. 1906 saw Buffalo’s first tall cylindrical grain-silos constructed using reinforced concrete. Europeans cited these monumental edifices as key examples of modernist functional design, featuring in the writings and photographs of Gropius, Le Corbusier, and others. Today the grain-silo’s dramatic, austere form remains. Inside, 50+years of decay alongside chaos —a dark labyrinth of derelict grain-handling equipment, machinery and workshops — produces powerful photographic testimony to the original functions — “in abandonment and death they evoke the majesties of a departed civilization”.
