Woolwich
The civil parish of Woolwich, roughly the area of the present-day wards Woolwich Riverside and Woolwich Common, was formerly known as Woolwich Saint Mary. Until 1842, when the Old Town Hall was built, the vestry met in a room in the parish church of St Mary Magdalene. Woolwich became part of the London metropolitan area in the mid-19th century, although was officially still in Kent at the time. In 1889, with the formation of London County Council, Woolwich became officially part of London. In 1900 the parishes of Woolwich, Eltham and Plumstead formed the Metropolitan Borough of Woolwich. In 1906 the new Woolwich Town Hall was inaugurated. In April 1965, following implementation of the London Government Act 1963, Woolwich was merged into the London Borough of Greenwich, since 2012 the Royal Borough of Greenwich. The administrative buildings of the borough are in Woolwich.
Horwich
Lying within the county boundaries of Lancashire since the 12th century, Horwich was a township in the historic ecclesiastical parish of Deane, in the Hundred of Salford. In 1837 Horwich joined with other townships and civil parishes to form the Bolton Poor Law Union and took joint responsibility for the administration and funding of the Poor Law in that area and built a workhouse in Farnworth. The Horwich Local board of health was established in 1872 and was superseded by Horwich Urban District of the administrative county of Lancashire in 1894. Under the Local Government Act 1972 Horwich Urban District was abolished in 1974 and its area became a successor parish of the newly created Metropolitan Borough of Bolton in Greater Manchester.
