Whether its big box chain stores or anonymous manufacturing facilities, wide, flat-faced buildings are a common sight on the route into Rochester, Minnesota, from the north. About five miles from downtown, the IBM Manufacturing & Training Facility has a similar boxy massing to other buildings on the street but has a distinctive blue facade pattern. From the air, the vast scale of this building can start to be understood in fact, when viewed from above, it resembles a computer chip. IBM Rochester is still the largest IBM facility under one roof, enclosing 3.6 million square-feet on 400 acres. In this city, IBMs frequent moniker Big Blue applies to both the company and the building. Commissioned in 1956 and designed by Eero Saarinen & Associates, the opening of the building in 1958 marks a key moment in IBMs design legacy and Minnesotas computing industry.泭泭
