Led by architectural historian Matt Postal, we’ll head east from the area that was originally planned as Hamilton Square to John Jay Park, viewing works by such notable architects as C.P.H. Gilbert, Harde & Short, and Richard Morris Hunt. Buildings intended to serve the common good will be frequently emphasized, as we discuss “model” tenements and related civic institutions, such as public schools, a Carnegie branch library, and a free dispensary built by Mt. Sinai Hospital.
