The Renaissance Center in Detroit, Michigan was built in the mid-70’s. At the time, the thought was that this new set of buildings would help provide for a ‘renaissance’ of the city of Detroit. Alas it wasn’t to be. The building was more of a fortress than anything else. It had large berms which faced the main street, and the other side was the river. This created a structure which was more of an island than anything else. A couple years ago, General Motors purchased the buildings and moved it’s world headquarters to it. There was a bit of irony in this, since the Renaissance Center (aka ‘RenCen’) had significant funding from the Ford family.
