The Mies van der Rohe Residential District in Lafayette Park was constructed between 1956 and 1963. Mies van der Rohe's work consists of three international style apartment towers and 186 townhouses. The facades of these buildings are noted for their walls of glass which integrate the interior and exterior spaces designed by noted landscape architect Alfred Caldwell. This Detroit neighborhood boasts the largest collection of Mies van der Rohe architecture in the world.
