The ongoing saga of Bertrand Goldberg’s Old Prentice Women’s Hospital continues, with members of the Save Prentice coalition delivering a petition with more than 3,500 signatures Monday to the offices of Mayor Rahm Emanuel, Alderman Brendan Reilly, and the Landmarks Commission.

They include Pritzker-winning architects as well as preservationists and ordinary citizens from Chicago and beyond. The Commission on Chicago Landmarks said earlier this month it would take up the issue before the end of their fall session, possibly as early as October 4. Emanuel, Reilly, and the Commission could grant landmark status to the iconic 1975 structure but have so far remained neutral on the issue.
