A recent news report from the Council on Tall Buildings and Urban Habitat cites fifty major, tall building projects worldwide that have been halted by a global economic downturn.

Last Friday, the Chicago Architecture Foundation’s “Chicago Model City” exhibit temporarily included the scale model of Santiago Calatrava’s “Spire” condominium project, the real one being on indefinite hold.  Asides from the model representation, the only physical evidence this project has left in Chicago is a large, circular foundation, commonly referred to as the “bathtub”.

Had the actual project been built, it would have been much taller than anything else in Chicago, including the Willis (nee Sears) Tower.

Guess which building is the Spire?
