Fourth Presbyterian Church at Open House Chicago

This masterpiece was designed by Ralph Adams Cram, a champion of the Gothic Revival style. It is the second-oldest building north of the river on Michigan Avenue; only the Water Tower and Pumping Station are older. The Tudor-style parish buildings were designed by Howard Van Doren Shaw. In 2012, the congregation dedicated an 80,000-square-foot addition, the Gratz Center, designed by Gensler. This bold contemporary addition to the Gold Coast is rhomboid in shape and clad in interlocking copper plates tinted a brilliant blue-green patina. The Gratz Center includes Buchanan Chapel, with a floor that incorporates a labyrinth modeled on the one at Chartres Cathedral in France. Visitors are welcome to view the Sanctuary at Michigan and Delaware and Buchanan Chapel on the second floor of the Gratz Center which is accessible from the sanctuary.
