The London Borough of Hounslow is a London borough in west London, England, forming part of Outer London. The borough was formed 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 plus the Heston and Isleworth Urban District of Middlesex. Hounslow covers a total area of around 21.61 square miles. The borough stretches from near Central London to the east towards the border with Surrey to the west, covering Chiswick, Brentford, Isleworth and Feltham along with Hounslow itself.
Hounslow grew quickly in the latter half of the twentieth century because of other travel, a connection to the largest of London's airports since the 1940s, Heathrow Airport which is inside the Hounslow post town.
The Great West Road, which crosses the borough from Chiswick to Heathrow, formerly served nationally and globally famous manufacturers like Firestone, Gillette and Coty. As a result, the borough became generally known as the 'Golden Mile'. A number of of these factory sites remain, such as Gillette Corner, and the Great West Road is still home to lots of prestigious names, providing them with easy 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.
