11. City College of New York: Great Hall
In 1907, City College moved up to this breathtaking Neo-Gothic campus. Built from the Manhattan schist bedrock on which they perch, the buildings are replete with white terra cotta ornament and a rich array of delightful grotesques reflecting the academic disciplines originally housed within. During OHNY Weekend, step inside of the iconic Shepard Hall to explore the soaring Great Hall, a jewel of architect George B. Post’s grand design and one of the largest rooms in all of New York City.
