The campus has 40 acres of gardens and the largest arboretum in BC's interior. Residences provide on-campus housing for 880 students. Kamloops, a small city of 90,280 people, is located in the semi-arid grasslands of the Thompson-Nicola region of British Columbia's southwestern interior, on the traditional lands of the Secwepemc (Shuswap) people. TRU has a satellite campus in Williams Lake in BC's Cariboo-Chilcotin region, and regional centres in 100 Mile House, Clearwater, Barriere, Ashcroft, and Lillooet. The Open Learning division reaches students worldwide. After one year operating out of the school district's various facilities, such as the Kamloops Indian Residential School building, Cariboo College moved to the current campus on McGill Road in September 1971, sharing the newly constructed Main Building with the Kamloops Vocational School. Much of the campus had been part of a Canadian Navy munitions base, and several of the officers' quarters built during that period were put to use and remain as heritage buildings on today's campus. Construction was a constant on Cariboo's campus to meet the needs of a rapidly expanding student body. The Library and the Gymnasium complex both opened in the fall of 1976. The Science building was completed in 1980, and the Visual Arts building opened the following year, replacing use of the Kamloops Indian Residential School facility. Construction began on student residences in 1988, and Hillside Stadium opened. 1989 saw the completion of the Clock Tower building and Alumni Theatre, and the addition of a second storey on the Main building's B Block for classroom and bookstore space. As part of Cariboo's application to become a university college in 1989, the first Campus Plan was developed, with the requirement that every building have an official name. Without a single faculty or function to identify it, the eighteen-year-old Main or Main Block building, as the oldest and still most central building on campus, officially became Old Main when Cariboo College became the University College of the Cariboo. Construction in the 1990s continued with the increasing influx of undergraduate students. UCC doubled the size of both the Library and Science buildings and opened the Computer Access Centre on Victoria Street in 1991, and completed the Arts and Education (A&E) building in two phases from 1991 to 1993. Next door to A&E, the 53,000 square foot Campus Activity Centre, including the campus bookstore, a cafeteria, pub, retail spaces, meeting rooms, and the student union office and coffee shop, opened in 1993 thanks to a cost-recovery-based joint proposal between UCC and the student society, after a change in legislation in 1990 allowed the college to borrow money privately for development.
