[In-person tour] This tour of Tribeca, focusing on its many cast-iron wonders, is a tribute to the legendary preservation advocate Margot Gayle, former member of the M.A.S. historic buildings committee and 1997 winner of the Society’s Jacqueline Kennedy Onassis Medal. Without Margot’s efforts, Tribeca likely would not be the protected historic neighborhood it is today. Your guide, Anthony W. Robins, first led a tour of cast-iron architecture in Tribeca in the mid-1970s, as a volunteer for Margot’s “Friends of Cast-Iron Architecture” (where he cut his teeth as a tour guide, later becoming co-chair of walking tours). This walk retraces the steps of that tour of 50 years ago, with special focus on the work of James Bogardus – one of Margot’s special interests – as well as facades cast by D.D. Badger’s Architectural Iron Works, the only major 19th-century iron foundry whose catalog still exists. Most of the iron buildings visited are city landmarks; Mr. Robins, on the LPC staff in the 1980s and ‘90s, wrote several of the relevant designation reports. For all tours, there are no refunds, cancellations, or exchanges unless we cancel a tour. Online registration closes one hour prior to the tour start time.
