The London Borough of Hounslow is a London borough in west London, England, forming a part of Outer London. The borough was established 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 the Heston and Isleworth Urban District of Middlesex. Hounslow covers a total area of about 21.61 square miles. The borough stretches from near Central London in the east towards the border with Surrey to the west, covering Chiswick, Brentford, Isleworth and Feltham in addition to Hounslow itself.
Hounslow grew swiftly in the latter half of the twentieth century as a consequence of 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 famous manufacturers including Firestone, Gillette and Coty. As a result, the area became known as the 'Golden Mile'. Some of these factory sites remain, for example Gillette Corner, plus the Great West Road is still residence to many prestigious names, supplying them with quick non-motorway access between Slough, London Heathrow Airport and Central London. Other notable landmarks consist of Osterley Park, Gunnersbury Park, Syon House, the London Museum of Water and Steam, and Chiswick House.
