Paddington is one of the ancient parishes of Middlesex. In 1889 it was transferred to the newly-created County of London, and in 1900 become Paddington Metropolitan Borough. Paddington Metropolitan Borough was abolished in 1965, becoming part of the City of Westminster.
Paddington is a district within the City of Westminster, in west London. Formerly a metropolitan borough, it was integrated with Westminster and Greater London in 1965. Three important landmarks of the district are Paddington station, designed by the celebrated engineer Isambard Kingdom Brunel and opened in 1847; St Mary's Hospital and Paddington Green Police Station (the most important high-security police station in the United Kingdom).
A major project called Paddington Waterside aims to regenerate former railway and canal land between 1998 and 2018, and the area is seeing many new developments.
