List of county exclaves in England and Wales 1844–1974


Until 1844, many of the counties in England and Wales had exclaves entirely surrounded by other counties. Under the Counties Act 1844, many of these exclaves were absorbed by the county within which they were located. Nevertheless, a number of exclaves remained; these were dealt with in a piecemeal manner over a period of decades.
The Local Government Act 1894 empowered the county councils of administrative counties to exchange areas in order to make a more effective local government area. As the Local Government Act 1888 had redefined the lieutenancy and shrievalty to be based on administrative counties, the changes also affected them as well as judicial boundaries. Accordingly, many anomalies in county boundaries were removed in the next three years, including the elimination of outlying areas of Derbyshire and Huntingdonshire.
The last major transfer of areas was in 1931, when the boundaries of Gloucestershire, Warwickshire, and Worcestershire were realigned. Following the creation of a new administrative county of Huntingdon and Peterborough in 1965, and boundary changes at Dudley in 1966, Flintshire was left as the only county with detached areas — these remained right up to the abolition of the county council in 1974.

Areas transferred

Bedfordshire

The county had no detached portions after 1844, and one abolished then:
The county had a detached portion or exclave consisting of the parishes of Llysfaen and Eirias and including the town of Old Colwyn, which was transferred to the surrounding county of Denbighshire and the urban district of Colwyn Bay in 1923. This was technically a semi-exclave, since it bordered the coast. In turn it surrounded a counter-semi-exclave of Denbighshire including the east part of Old Colwyn, which had very complex borders. This counter-semi-exclave in turn contained a counter-counter-semi-exclave of Caernarvonshire, that of "Coed-coch Cottage" covering 1.6 acres.

Denbighshire

The major semi-exclave of Caernarfonshire contained a semi-exclave of Denbighshire including the east part of Old Colwyn. This in turn had two semi-exclaves north of Penmaen-Rhôs, separated by a very narrow corridor. In addition, it was accompanied by two small true exclaves forming thin strips south-east of Old Colwyn. This total of five detached portions of Denbighshire belonged to the parish of Llandrillo yn Rhos, and was annexed to the semi-enclave of Caernarfonshire in 1879.

Derbyshire

Gloucestershire

After 1844, Gloucestershire had no true exclaves. However, the north of the county had two pene-enclaves which were only joined to the rest of the county by narrow necks of land. These became Marston Sicca Rural District, Campden Rural District and Pebworth Rural District. In 1931 the county's boundaries with Warwickshire and Worcestershire were realigned, removing the salients from Gloucestershire; in compensation, Gloucestershire gained a number of detached Worcestershire parishes.

Hampshire

was an exclave of the administrative county of Lancashire, separated from the rest of the county by the County Borough of Oldham, and enclosed on the other side by Saddleworth Urban District in the West Riding of Yorkshire. The urban district was abolished by the Local Government Act 1972, taking effect on 1 April 1974, with its former area transferred to the newly created metropolitan county of Greater Manchester, along with much of Salford Hundred, to form part of the new Metropolitan Borough of Oldham, where it was also joined by Saddleworth.
Additionally, the North Lonsdale area of Lancashire, or "Lancashire north of the sands", was cut off from the main body of Lancashire by Westmorland and Morecambe Bay. This area was transferred to Cumbria by the Local Government Act 1972.

Middlesex and the County of London

When the County of London was made in 1889, it was made up of parishes from Kent, Surrey and Middlesex. One Middlesex parish, Clerkenwell, had a detached part that became an exclave of London surrounded by Middlesex. The area – a residential area of north-central Muswell Hill – was absorbed by Middlesex in 1899.
The formation of the County of London severed two small parts of the parish and urban district of South Hornsey to fall within it. This lasted ten years, then the whole of South Hornsey passed to the County of London. At the same time, the distant Muswell Hill outlier of the parish of Clerkenwell was transferred to Middlesex.

Staffordshire

In 1889, the extra-parochial place of Dudley Castle, formerly in Worcestershire, became an exclave of Staffordshire, surrounded by the county borough of Dudley, itself an exclave of Worcestershire. In 1894, the area became the only parish in Dudley Rural District. In 1929, it was absorbed by the civil parish and county borough of Dudley.

Warwickshire

, Stretton-on-Fosse, and Whitchurch formed an exclave of Warwickshire, separated from the main part of the county by an exclave of four Worcestershire parishes. In 1931, the intervening area of Worcestershire was transferred to Warwickshire, so that the three parishes became joined to the rest of the county.
