The London Borough of Hounslow is a London borough in west London, England, forming 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 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 as well as Hounslow itself.
In accordance with population estimates from the middle of 2014, the borough features a permanent population of around 265568 inhabitants.
The Great West Road, which crosses the borough from Chiswick to Heathrow, once served nationally and globally famous manufacturers such as Firestone, Gillette and Coty. As a result, the area became referred to as the 'Golden Mile'. A number of of these factory sites remain, like Gillette Corner, and the Great West Road is still home to several prestigious names, supplying them with straightforward 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.
