The London Borough of Hounslow is a London borough in west London, England, forming a part of Outer London. The borough was created in 1965, under the London Government Act 1963, by the merger of the area of the former Brentford and Chiswick Urban District, Feltham Urban District and also the Heston and Isleworth Urban District of Middlesex. Hounslow covers a total area of around 21.61 square miles. The borough stretches from close to Central London to the east towards the border with Surrey to the west, covering Chiswick, Brentford, Isleworth and Feltham as well as Hounslow itself.
Hounslow grew quickly in the latter half of the twentieth century resulting from other travel, a connection to the largest of London's airports since the 1940s, Heathrow Airport which is in the Hounslow post town.
The Great West Road, which crosses the borough from Chiswick to Heathrow, formerly served nationally and globally renowned manufacturers including Firestone, Gillette and Coty. Consequently, the borough became called the 'Golden Mile'. Several of these factory sites remain, for example Gillette Corner, plus the Great West Road is still home to quite a few prestigious names, supplying them with straightforward non-motorway access between Slough, London Heathrow Airport and Central London. Other notable landmarks include Osterley Park, Gunnersbury Park, Syon House, the London Museum of Water and Steam, and Chiswick House.
