The London Borough of Hounslow is a London borough in west London, England, forming 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, along with the Surrey borough of Spelthorne. The local authority is Hounslow London Borough Council.
In line with population estimates in the middle of 2014, the borough features a permanent population of roughly 265568 individuals.
The Great West Road, which crosses the borough from Chiswick to Heathrow, in the past served nationally and globally famous manufacturers like Firestone, Gillette and Coty. As a result, the area became generally known as the 'Golden Mile'. Some of these factory sites remain, like Gillette Corner, and the Great West Road is still home to numerous prestigious names, supplying them with simple 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.
