Many of the buildings surrounding the square are devoted to providing, researching and administering health care. Two hospitals, the National Hospital for Neurology and Neurosurgery (NHNN), often referred to synechdochally as "Queen Square", and the Royal London Hospital for Integrated Medicine (formerly the Royal London Homoeopathic Hospital), make up the east side of the square. The Institute of Neurology, part of University College London (UCL), is located in the north east corner of the square. The former Institute for Public Health takes up much of the north side - the building is now used as the administrative centre for the NHNN and Institute of Neurology.
