Copenhagen University Hospital forms a conglomerate of several hospitals in Region Hovedstaden and Region Sjælland, together with the faculty of health sciences at the University of Copenhagen; Rigshospitalet and Bispebjerg Hospital in Copenhagen belong to this group of university hospitals. Rigshospitalet began operating in March 1757 as Frederiks Hospital, and became state-owned in 1903. With 1,120 beds, Rigshospitalet has responsibility for 65,000 inpatients and approximately 420,000 outpatients annually. It seeks to be the number one specialist hospital in the country, with an extensive team of researchers into cancer treatment, surgery and radiotherapy. In addition to its 8,000 personnel, the hospital has training and hosting functions. It benefits from the presence of in-service students of medicine and other healthcare sciences, as well as scientists working under a variety of research grants. The hospital became internationally famous as the location of Lars von Trier's television horror mini-series ''The Kingdom''. Bispebjerg Hospital was built in 1913, and serves about 400,000 people in the Greater Copenhagen area, with some 3,000 employees. Other large hospitals in the city include Amager Hospital (1997), Herlev Hospital (1976), Hvidovre Hospital (1970), and Gentofte Hospital (1927).
