Mies settled in Chicago, Illinois where he was appointed head of the architecture school at Chicago's Armour Institute of Technology.
One of the benefits of taking this position was that he would be commissioned to design the new buildings and master plan for the campus. All his buildings still stand there, including Alumni Hall, the Chapel, and his masterpiece the S.R. Crown Hall, built as the home of IIT's School of Architecture. Crown Hall is widely regarded as Mies' finest work, the definition of Miesian architecture.
