West Harrow is a locality directly to the west/southwest of Harrow town in the London Borough of Harrow, in the county of Greater London and historically in the county of Middlesex.
West Harrow is located on the western side of Harrow, roughly covering the area to the west of Bessborough Road, to the south of Pinner Road and to the north of Whitmore Road. To the south east of West Harrow is Harrow on the Hill, to its north east is the town centre of Harrow, to its west is Rayners Lane, to its north is North Harrow, and to its south are Roxeth and South Harrow.
Harrow is the second safest borough in the Greater London Authority area.[2]
Prior to the early 20th century, the area was overwhelmingly rural. The construction of the Uxbridge extension to the Metropolitan line in 1904, and specifically the new West Harrow tube station, triggered a steady growth of housing developments in the area, spreading out from the location of the new station and giving the area a new identity.
