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 along with 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 to the border with Surrey in the west, covering Chiswick, Brentford, Isleworth and Feltham in addition to Hounslow itself.
Hounslow grew rapidly during 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, once served nationally and globally famous manufacturers like Firestone, Gillette and Coty. As a result, the borough became called the 'Golden Mile'. A few of these factory sites remain, including Gillette Corner, and the Great West Road continues to be home to many prestigious names, providing 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.
