Chiswick is a large suburb of west London, England and part of the London Borough of Hounslow. It is located on a meander of the River Thames, 6 miles (9.7 km) west of Charing Cross and is one of 35 major centres identified in the London Plan. It was historically an ancient parish in the county of Middlesex, with an agrarian and fishing economy. Having good communications with London from an early time the area became a popular country retreat, and as part of the suburban growth of London in the late 19th and early 20th centuries the population of Chiswick significantly expanded. With neighbouring Brentford, it became a municipal borough in 1932 and has formed part of Greater London since 1965.
