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.
Caterham
Before 1889 Caterham was the most eastern market town of a Surrey that stretched north to Southwark. North eastern parts of the county were absorbed gradually, in part by the County of London in 1889 (to South Norwood and Wimbledon which as a result have London Postcodes) and then to towns and villages within the present boundaries that form Greater London in 1965. From 1885 Oxted and Godstone developed from villages to towns. Tandridge District formed on 1 April 1974, under the Local Government Act 1972, by the merger of Caterham and Warlingham urban district along with Godstone Rural District.
