The University's Main Campus covers about 16 hectares of land in the Bonham Road/Pokfulam area of Hong Kong Island and accommodates eight of the ten faculties, namely Architecture, Arts, Business and Economics, Education, Engineering, Law, Science and Social Sciences, as well as the Main Library. A major building programme which began in the 1970s has seen the construction of many modern buildings on the Main Campus. These modern buildings stand adjacent to several retained older buildings, including the original Main Building which dates from 1912, which have been preserved because of their historic and architectural merits.
The University of Hong Kong has built a major extension, the Centennial Campus, immediately to the west of the existing Main Campus. The new campus, located against an attractive backdrop of tree-clad hillsides, will be served by a Mass Transit Railway station and provides academic buildings, recreational facilities and other modern amenities. It houses the Faculties of Arts, Social Sciences and Law, with a state-of-the-art learning commons, a lecture centre and experimental teaching/learning spaces. A large landscaped area of 4,000 square metres can be found on top of the re-provisioned service reservoirs of the Water Supplies Department.
The Sassoon Road Campus which is situated three kilometres to the southwest of the Main Campus mainly houses the departments of the LKS Faculty of Medicine. Clinical teaching facilities are based in the Queen Mary Hospital which is one of the University’s teaching hospitals, and pre-clinical teaching facilities and library services are close by. The two major buildings for the Medical Faculty, i.e. William M.W. Mong Block and the Laboratory Block, provide state-of-the-art facilities for pre-clinical and clinical research and teaching. Other teaching and/or research facilities in the vicinity include the HKU Pasteur Research Centre and the School of Chinese Medicine. The Hong Kong Jockey Club Building for Interdisciplinary Research houses multi-disciplinary research activities for the betterment of human health and welfare.
The Faculty of Dentistry has its clinical teaching facilities and library services in the Prince Philip Dental Hospital in Sai Ying Pun, a short distance to the north of the Main Campus.
Student residential accommodation is provided in a limited form on the Main Campus and the bulk of the accommodation is situated further south along Pokfulam Road and on Sassoon Road and Lung Wah Street.
Sports facilities, mainly indoors, are provided at Flora Ho and Lindsay Ride Sports Centres, with the University's major sports fields being located in the Sandy Bay (Sha Wan) area with provision for athletics, softball, soccer, hockey and lacrosse, etc. A 50-metre outdoor swimming pool, tennis courts and a multi-purpose sports area round off a most comprehensive facility.
Other parts of the University's estate include the Kadoorie Institute, which occupies 9.5 hectares of land in the New Territories, and the Swire Institute of Marine Sciences on the southern coast of Hong Kong Island.
The University is a smoke-free Campus. There is a total smoking ban, both indoors and outdoors.
