Holby City Hospital is the fictional hospital within the city in which Casualty and Holby City are set. It is based on the Bristol Royal Infirmary which the original script writers spent time observing in the 1980s in order to garner ideas for Casualty. Although both shows are set in the same hospital, Casualty is primarily filmed in Cardiff, whilst Holby City was filmed in Hertfordshire at BBC Elstree Centre. The indoor shots for the first series of Casualty were filmed at BBC Television Centre in London. The exterior shots of the hospital used in Casualty were formerly filmed at the City of Bristol College; location filming later moved to an industrial estate at , close to the interior set of the hospital. It was announced on 15 October 2008 that the BBC was considering moving the filming of Casualty to studios in Cardiff. On 26 March 2009, the BBC confirmed the move. Since late 2011, Casualty has been filmed on a purpose built studio and backlot set at the BBC Roath Lock Studios in Cardiff Bay at

As of 2002, four main wards have formed the focus of storylines within the hospital. In Casualty, the primary location is the hospital's Emergency Department (formerly referred to as Accident and Emergency), which has its own adjoining Clinical Decisions Unit, introduced in series 25. Holby City is set between the hospital's Acute Assessment Unit (ground floor), and Keller (third floor) and Darwin (sixth floor) wards, providing General and Cardiothoracic surgical care respectively. Holby expanded by adding "HolbyCare", a private healthcare ward led by Michael Spence adjacent to the existing Intensive Care Unit on the fifth floor. Former storylines have also focused around the hospital's Otter ward, providing pediatric care, as well as its maternity ward. Otter ward has not featured in the show since series 4, whilst the maternity ward ceased usage as a primary location in series 8. Obs & Gynae, Maternity and pediatrics are quite regularly mentioned. In 2004, Nightingale, a mothballed wing of the hospital, is used to perform a major heart transplant on a small girl by Connie Beauchamp and Harry Harper while the hospital burns. In 2011, Downton and Perry are shown to be psychiatric wards at the hospital. (Series 25, Episode 23 "Place of Safety") Other wards of the hospital to be referenced in the series include Berkley, Clifton, Curie (disused), Florence, Geraint Morris, Hitchcock (psychiatric), Linnaeus, Swift and St Clares as well as the paediatric, neonatal, burns and neuro ICUs.
