About Harrow on the Hill

Harrow on the Hill formed an ancient parish and later civil parish in the Gore hundred of Middlesex. In 1831 it had a population of 3,861 and occupied an area of 9,870 acres (39.9 km2). There were significant boundary changes in 1894, when the bulk of the parish was removed to create the parishes of Harrow Weald, Wealdstone and Wembley.

By 1931 it occupied a reduced area of 2,129 acres (8.62 km2) and had a population of 26,380. It formed the Harrow on the Hill Urban District of Middlesex from 1894 and was abolished by a County Review Order in 1934, with the bulk of the area forming part of a new civil parish and urban district of Harrow. In 1954 the urban district was incorporated as the Municipal Borough of Harrow and in 1965 it was transferred to Greater London to form the London Borough of Harrow.
