List of county exclaves in England and Wales 1844–1974

[1] Nevertheless, a number of exclaves remained; these were dealt with in a piecemeal manner over a period of decades.

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 following list has 204 exclaves in total, including 11 semi-exclaves with a coastline and generating 76 legal issues.

The 1844 Act resulted in a list of individual legal enactments targeting boundary anomalies.

Counter-exclaves were not regarded as separate legal issues, because they vanished when the exclave concerned was abolished.

Technically this left a short stretch of the River Thames tidal foreshore in Southwark as a riparian semi-exclave of the city, just east of the present London Bridge.

Previously, two fields of Lutton Lodge Farm formed a pene-exclave with an isthmus only about two yards wide.
