The Quadrangle is Rensselaer's largest and oldest residence area. Built in 1919, it was completely renovated and reopened in 1988. The Quad houses 450 students in single, double, and triple rooms. It is divided into 19 units, each with its own entry. Each has a small kitchen on the first floor and a study-lounge on the second. Residents on the first and second floors share a bath with the adjacent room, while students on the third share a floor bath. All rooms are air cooled and carpeted.
