The former Prentice Women’s Hospital, the shuttered modernist medical facility designed by Marina City architect Bertrand Goldberg, was today named among this year’s 11 most-endangered historic places in America by the National Trust for Historic Preservation.

The Washington D.C.-based non-profit organization called the building Goldberg’s “tour de force” that “like many of Goldberg’s architectural wonders in Chicago…still has no formal protection from demolition.” The 36-year-old building has been the subject of a heated preservation battle triggered when Northwestern University announced plans to demolish the ionic structure for a new research facility.

Other buildings on this year’s National Trust’s America’s Most Endangered Places list include the vacant and dilapidated Long Island N.Y. house where jazz saxophonist John Coltrane wrote A Love Supreme and other sites.

The Trust’s announcement will be formally made at a 11am rally near Prentice on the corner of Huron and McClurg Ct.  The local chapter of the modernist preservation group DoCoMoMo, Landmarks Illinois and Preservation Chicago are among the participants.
