It sits on the traditional territory of the Neutral, Anishnaabeg, and Haudenosaunee peoples that is part of the Haldimand Tract, land promised to the Six Nations that includes six miles on each side of the Grand River. It is bordered by Waterloo Park to the south, Wilfrid Laurier University to the southeast, residential neighbourhoods to the northeast, east and west, and the Laurel Creek Conservation Area to the northwest. Three numbered roads also intersect the main campus: University Avenue West, Columbia Street West, and Westmount Road North. While the main campus is , the majority of the teaching facilities are centred on a ring road in its southern portion. The oldest building on campus is the Graduate House, originally a farmhouse dating back to the 19th century. The oldest building which was erected for the university is the Douglas Wright Engineering Building, which was erected in 1958. A large majority of the university's buildings, and its ring road, were constructed during the 1960s. The university's main campus is divided into three major areas: South Campus, North Campus and Northwest Campus. South Campus is the academic core of the university, while North Campus holds the Research and Technology Park. Northwest Campus is the least developed area of the main campus, made up primarily of farm fields and an environmental reserve, which divides it from North Campus. In addition, the university owns several other properties in Cambridge, Huntsville, Kitchener, and Stratford, Ontario. The Ion rapid transit system provides a transit connection between the main campus, and several off-campus facilities, including the university's start-up incubator program in Kitchener. Libraries and museums The university has four libraries housing more than 1.4 million books, as well as electronic resources including e-books, serial titles, and databases. Three libraries are on campus: the Dana Porter Library, housing material relating to arts, humanities and social science, the Davis Centre Library, housing material for engineering, mathematics and science, and the Witer Learning Resource Centre, housing material for the School of Optometry and Vision Science. The fourth library, the Musagetes Architecture Library, is in Cambridge, alongside the university's School of Architecture. The libraries of the university's affiliated colleges are also considered a part of the university's library system. Doris E Lewis was the first University Librarian. The university's library system
