My favorite buildings in Chicago are by Bertrand Goldberg, architect of slightly eccentric buildings throughout the Windy City including the Marina City Towers, River City and Prentice Women’s Hospital on Northwestern University’s Medical Campus in the heart of Chicago. A few years ago the university moved out of the building and it has sat vacant. Northwestern University has recently made rumblings about demolishing the building to make way for a newer – and probably more bland – building. The National Trust for Historic Preservation has a Save Prentice Petition asking you to “Show Prentice Some Love.”
