Located on 114th Street on the southeast-corner of the Morningside campus's main quadrangle, John Jay Hall is a large residence hall for first-year students. The building's lower floors also house a large dining hall, a small convenience store, and the Health Center.
John Jay Hall has mostly single-occupancy rooms, and each hallway has shared men's and women's bathrooms. You can check out what a single-occupancy room looks like in this virtual tour.
The building's name may sound familiar since New York City is also home to John Jay College, one of the eleven senior colleges in the CUNY system. John Jay College is one of the top in the country for preparing students to work in law enforcement and criminal justice. John Jay was a Columbia graduate and the first Chief Justice of the Supreme Court.
