The Chicago Spire

The Chicago Spire was a super tall skyscraper project at 400 N. Lake Shore Drive in Chicago, Illinois that failed financially after beginning construction. When originally proposed as the Fordham Spire in July 2005, the design had 116 stories and would have included a hotel and condominiums and been topped with a broadcast antenna mast. The design was by Spanish architect Santiago Calatrava, and Chicago developer Christopher T. Carley of the Fordham Company was spearheading the project.
