Wilder Hall (Student Union) serves as a gathering place for students, faculty, staff, alumni, and guests. Originally a residence hall for about 65 men, the building was completed in 1911 with funding from an anonymous donor. The donor was later identified as Herbert Wilder, a Boston paper manufacturer.
The building also had a dining room, a billiard room, bowling alley, library, a reception room for women students, a barbershop, and other spaces for meetings and assembly. The broad terrace flanking the main entry was designed for rallies and songfests.
While no longer a residence hall, Wilder Hall has several community meeting rooms, office space for student organizations, and a student lounge. It also houses the Office of the Dean of Students, Office of Student Activities, Office of Religious and Spiritual Life, Conference Services, the International Student Resource Center, and the Student Mail Room.
The lower level of Wilder Hall features a food market and a student-run performance and dance venue.
