The Royal London Hospital is a large teaching hospital in Whitechapel in the London Borough of Tower Hamlets. It is part of Barts Health NHS Trust. It provides district general hospital services for the City of London and Tower Hamlets and specialist tertiary care services for patients from across London and elsewhere. The current hospital building has 1248 beds and 34 wards. It opened in February 2012. The hospital was founded in September 1740 and was originally named the London Infirmary. The name changed to the London Hospital in 1748, and in 1990 to the Royal London Hospital. The first patients were treated at a house in Featherstone Street, Moorfields. In May 1741, the hospital moved to Prescot Street, and remained there until 1757 when it moved to its current location on the south side of Whitechapel Road, Whitechapel, in the London Borough of Tower Hamlets. The hospital's roof-top helipad is the London's Air Ambulance operating base. Source: Wikipedia (en)
