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 plus the Heston and Isleworth Urban District of Middlesex. It borders the boroughs of Richmond upon Thames, Hammersmith and Fulham, Ealing and Hillingdon, in addition to the Surrey borough of Spelthorne. The local authority is Hounslow London Borough Council.
In line with population estimates from the middle of 2014, the borough includes a permanent population of approximately 265568 individuals.
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 generally known as the 'Golden Mile'. Some of these factory sites remain, like Gillette Corner, and the Great West Road continues to be home to quite a few prestigious names, providing 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.
