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. 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 from the middle of 2014, the borough has a permanent population of around 265568 people today.
The Great West Road, which crosses the borough from Chiswick to Heathrow, previously served nationally and globally famous manufacturers including Firestone, Gillette and Coty. Because of this, the borough became known as the 'Golden Mile'. A few of these factory sites remain, like Gillette Corner, and also the Great West Road is still home to quite a few prestigious names, supplying them with quick 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.
