a strongly entrenched "[c]olonial mentality" at Wits, along with "high capitalism, the new liberalism and communism of a South African kind, combined with entrenched white settler mores (particularly in the Engineering and Science faculties) ... the university ... was an arena of conflicting positions generally contained within polite academic conventions". The 1970s saw the construction of Jubilee Hall and the Wartenweiler Library, as well as the opening of the Tandem Accelerator; the first, and to date only, nuclear facility at a South African university. In 1976, Lawson's Corner in Braamfontein was acquired and renamed University Corner. Senate House, the university's main administrative building, was completed in 1977. The university underwent a significant expansion programme in the 1980s. The Medical School was moved to new premises on York Street in Parktown on 30 August 1982. Additionally, in 1984 the university acquired the Milner Park showgrounds from the Witwatersrand Agricultural Society. These became West Campus, with the original campus becoming East Campus. In 1984, the Chamber of Mines building opened. A large walkway named the Amic Deck was constructed across the De Villiers Graaff Motorway which bisects the campus, linking East Campus with West Campus. The 1980s also witnessed a period of heightened opposition to apartheid, as the university struggled to maintain its autonomy in the face of attacks from the apartheid state. Wits looked anew to the "Open Universities" statement of 1957, to which the University of the Western Cape now also added its voice. As the apartheid government attempted, through the threat of financial sanctions, to bring Wits under firmer control, protest escalated culminating in the General Assembly of 28 October 1987, at which the university reiterated its commitment to the values underlying the "Open Universities" statement. University management itself came under increasing grassroots pressure to implement change within the university. A Wits-initiated research project, Perspectives of Wits (POW), published in 1986, revealed a surprising disconnect between the perceptions disadvantaged communities had of Wits and the image Wits had been attempting to convey of itself as a progressive opponent of apartheid. POW, which had involved interviews with members of organisations among disadvantaged communities in the PWV area, international academics, students and staff at Wits, and even a meeting with the then-banned ANC in Lusaka, revealed that to many in the surrounding disadvantaged communities, there was a perception of Wits as an elitist institution dominated by white interests.
