Architects are often driven by forces which are stronger than aesthetics or even client whims and desires.

One of the first and most successful examples of urban renewal, Detroit's 78-acre Lafayette Park is known for being the world's largest collection of works by Mies van der Rohe. Now, the mid-century modern "masterpiece" is the first urban renewal project to be declared a National Historic Landmark. This is partially due to the fact that, as Ruth Mills, architectural historian for Quinn Evans Architects told the Detroit Free Press, "Lafayette Park was one of the few urban renewal projects that's done it successfully." It is now Michigan's 41st landmark.
