the wrong side of it. Most of the border has been superseded, but a portion remains between the boroughs of Stockport and Tameside south of Denton, and this still illustrates the problem. Leicestershire The county had no exclaves, except sixteen small counter-exclaves in its large enclave of Derbyshire (q.v.) (pre-1844 total 16, legal 0; post-1844 total 16, legal 0): Appleby Magna (4). Donisthorpe (12). Lincolnshire The county had three exclaves after 1844 (pre-1844 total 3 legal 1; post-1844 total 3, legal 1): Misson (3). The parish of Misson was shared with Nottinghamshire, which had the village. Lincolnshire had one main exclave, Misson Springs, with two satellite exclaves of Highwood Farm and Lewes Farm. The latter was only separated from the main exclave by the width of Springs Road. The parish was consolidated within Nottinghamshire in 1886, despite being a riparian semi-exclave cut off from the rest of the county by the River Idle. City of London The City of London has kept its ancient boundaries, which have no exclaves. However, the entire length of Old London Bridge was in its territory, until it was demolished in 1831. 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. Middlesex and the County of London There had been only one historical exclave of the county, abolished before 1844: Liberty of St Martin's Le Grand. This had been a medieval college of secular canons, with a collegiate church, situated in the City of London parish of St Leonard, Foster Lane. The college was taken over by Westminster Abbey in 1503 as part of the endowment granted for the upkeep of the Henry VII Chapel, and subsequently was regarded as part of the borough of Westminster up to the Reform Act 1832, and an exclave of Middlesex. This was despite an Act of 1815 annexing the Liberty to the Aldersgate Ward of the City of London when the site was earmarked for a new General Post Office. When the County of London was constituted in 1889, it was made up of parishes from Kent, Surrey and Middlesex. Whereas Middlesex had no county exclaves, it had several parish exclaves and three of these caused anomalies in the new county's boundaries: One Middlesex parish, Clerkenwell, had a detached portion that became an exclave of London surrounded by Middlesex.
