Guy’s and the Royal Merger tie The Royal Dental Hospital School of Dental Surgery – ‘the Royal’, merged with the dental school of the United Medical and Dental Hospitals of Guy’s and St Thomas’ in 1985 – an occasion marked, in part by this tie. The Royal vacated its building in Leicester Square, now The Radisson Blu Edwardian Hampshire Hotel, and moved to the Guy’s Campus at London Bridge. Memory of the ' the Royal’ continues to be kept alive by its Old Staff and Students Association (OSSA) -see below.
