The U.K. TV drama series 'Casualty' is set in the A&E (Accident and Emergency) department of which fictional hospital?

'Casualty' is a British medical drama series that airs weekly on BBC One. It is the longest-running emergency medical drama television series in the world, and the most enduring medical drama shown on prime time television in the world. Created by Jeremy Brock and Paul Unwin, it was first broadcast in the United Kingdom on BBC One on 6 September 1986. The original producer was Geraint Morris.

The programme is set in the fictional Holby City Hospital and focuses on the staff and patients of the hospital's Accident and Emergency Department. The show has very few ties to its sister programme Holby City, which began as a spin-off from Casualty in 1999, set in the same hospital. Casualty is shown weekly on a Saturday evening, which has been its time slot since the early 1990s.

The 1,000th episode of Casualty aired on 25 June 2016. A feature-length 30th anniversary episode of Casualty aired on 27 August 2016, episode 1 of series 31. For the series 31 finale, creator Paul Unwin returned to write a special episode which was entirely recorded in one take using only one camera, five boom operators and forty microphones.
