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 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 close to Central London to the east towards the border with Surrey towards the west, covering Chiswick, Brentford, Isleworth and Feltham along with Hounslow itself.
In line with population estimates in the middle of 2014, the borough has a permanent population of roughly 265568 people.
The Great West Road, which crosses the borough from Chiswick to Heathrow, at one time served nationally and globally well-known manufacturers including Firestone, Gillette and Coty. As a result, the area became referred to as the 'Golden Mile'. Several of these factory sites remain, for example Gillette Corner, plus the Great West Road continues to be home to a lot of prestigious names, providing 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.
