Perelman Quadrangle, Philadelphia

The Perelman Quadrangle comprises a set of event venues situated on the campus of the University of Pennsylvania, located in the University City area of Philadelphia. The Perelman Quadrangle primarily revolves around a central plaza located between Houston and College halls, with additional event spaces spread out across the wider Penn campus.

Houston Hall, constructed in 1895, serves as Penn's student union building and is considered by some as the first of its kind in the United States. In 1978, it was listed as a contributing property in the National Register of Historic Places within the University of Pennsylvania Campus Historic District. Today, Houston Hall houses a cafeteria, various dining options, study rooms, auditoriums, and numerous meeting rooms and offices.

College Hall, Penn's inaugural building on its West Philadelphia campus, dating back to 1871, stands just across the plaza and accommodates most of the university's classrooms and administrative spaces.

Additionally, facing the plaza are Claudia Cohen Hall, initially constructed in 1874, and Irvine Auditorium, completed in 1932. Originally known as Logan Hall, Cohen Hall currently houses administrative offices, meeting rooms, and several academic departments. It was originally built for the university's medical school, later serving as the home of the dental school and subsequently the Wharton School. The Irvine building boasts a grand auditorium featuring a significant pipe organ gifted by Cyrus Curtis, and it also includes various smaller performance and rehearsal spaces. Williams Hall, built in 1972, overlooks the plaza and contains offices and classrooms for humanities and language departments.
