The main campus sits on 756 acres in
DeKalb and includes 64 major buildings. Additional campus sites include the Lorado Taft Field Campus (144 acres), Rockford Campus (10 acres), and the Naperville Campus (11.2 acres). On the level below the auditorium, the original gym was transformed into a computer classroom. Also on the same level is the NIU Art Museum which occupies two large spaces. The East Lagoon near Altgeld is a recreation spot on campus. The Holmes Student Center also houses a 78-room hotel.
Residence halls NIU's residence halls provide several living options to on-campus students. As of 2024, there are six student
dormitories and complexes. Living-learning floors include the Health Professions House; Business Careers House; Teacher Education and Certification House; Honors House; International House; Science, Technology, Engineering & Mathematics House; and Fine Arts House. Northern View Community, which opened in 2008, offers apartments to undergraduate students who are at least two years post-high school, graduate students, law students, or any student who has a dependent and/or a partner or spouse. The Fanny Ruth Patterson Complex, a 1,000-bed complex just north of Lincoln Hall, opened to all students in the fall of 2012. It features two residential buildings where students can live in clusters of 12.
Athletic facilities On the west side of campus is
Brigham Field at Huskie Stadium, the home of NIU football games, which also often hosts other outdoor events. Huskie Stadium, which has a seating capacity over 23,000, is surrounded by large open grassy areas which provide recreation, and also serve as the
tailgating lots for football games. There is also a baseball field,
Ralph McKinzie Field; a softball field, Mary M. Bell Field; a soccer field, Huskie Soccer Complex; and tennis courts, Gullikson Tennis Courts, which flank Huskie Stadium. At the stadium's north end zone are two athletic buildings. The first is the Jeffrey and Kimberly Yordon Academic and Athletic Performance Center. The facility opened in August 2007. The second is the Kenneth and Ellen Chessick Indoor Practice Center, an 80,600-square-foot practice facility that houses the football, baseball, and softball teams. On the far west side of campus is the
Convocation Center, a 10,000-seat arena opened in 2002. The Convocation Center hosts NIU men's and women's basketball, gymnastics, wrestling, and volleyball, Victor E. Court, games, the opening convocation ceremony for incoming freshmen, music concerts, and a variety of events throughout the year including job fairs, internship fairs, and other expositions. At the corner of Annie Glidden Road and Lucinda Avenue is the
Chick Evans Field House, home to two large activity rooms with mirrors often used by dance clubs; a three-lane, 1/7-mile jogging and walking track; four multipurpose courts for basketball, volleyball, indoor soccer and floor hockey; and a cardio- and strength-training room, which has been under-used since the basketball team moved to the Convocation Center. The field house continues to host expositions and sporting events of a smaller scale, and is the headquarters for the campus
ROTC program. Two swimming pools are located in Anderson and Gabel Halls. ==Academics==
