Holby Holby Holby is a fictional city in the United Kingdom, the setting for the BBC medical dramas "Casualty" and "Holby City", and the police drama "HolbyBlue". It is based on the real city of Bristol, where "Casualty" was formerly filmed, and is notionally located in the fictional county of Wyvern in South West England, not far from the border with Wales. While "Casualty" has been filmed in Cardiff since 2011, "Holby City" is filmed in Elstree, Hertfordshire. Both shows are set in the same fictional Holby City Hospital. Holby has an airport called Holby International. Holby City Hospital is the
University Hospital Lewisham on the roof. In 2012, architects AWW worked with the hospital to re-plan five wards and medical facilities whilst maintaining the Emergency Department. The expanded facilities improve efficiency with the addition of a new Children's Emergency Department, Urgent Care Centre and new emergency x-ray facilities. In July 2012, South London Healthcare NHS Trust was put into financial administration. A government report in 2012 recommended that three SLHT hospitals should be taken over by nearby NHS trusts and that the University Hospital Lewisham Accident and Emergency unit should close, with A&E patients instead going to the SLHT-run Queen Elizabeth Hospital in
