Its name came from Anglo-Saxonburg-steall "fort site" or "place of refuge", likely referring to the hill there. The hill is now the home to Fort Borstal. However, local resident Donald Maxwell argued that a 'borstal' was "a track up a chalk hill", claiming to have heard local farmers use the term in this way. The village is mentioned in the Domesday Book of 1086 as Borchetelle, and then consisted of a 50-acre meadow, six households and two watermills. By 1769 this riverside farm was called Bostle, and probably had been joined by a wayside inn called the White Horse on the valley road above. In about 1830 Borstal House was built near the farm, and at the time of the 1840s Tithe Map the settlement was just a hamlet of a few cottages, mostly owned by local woman Mary Tuff. She sold her nearby lime-works in 1853, which was developed into a cement factory owned from 1864 by London solicitor Samuel Barker Booth. Its success led to the hamlet's growth into a village of terraced houses with two new pubs, shops and a workmen's institute. A second cement factory, called Borstal Manor, opened in 1898 near the original Domesday settlement. Both works closed in 1900, but continued to produce cement intermittently until about 1920. The village went into a decline when its factories closed, but underwent a resurgence of new house-building in the 1930s, when it became a suburb of Rochester. Borstal House, by then renamed Borstal Manor, was demolished in about 1960. The western end of the Domesday meadow is now crossed by the M2 motorway and the Channel Tunnel Rail Link. The rest of it has been built on. The parish church, built in 1879, is dedicated to St Matthew. It was built on land donated by Mary Tuff's son Thomas, who also dedicated a window in the church to Saints Matthew and Margaret. Another window is dedicated to Marian Tuff, the wife of Rochester MP Charles Tuff Jnr, and her sister Martha Emily Browne. The noted artist Donald Maxwell lived at No. 3 Borstal Villas from 1908 to 1930.
Fort Borstal
Fort Borstal was built as an afterthought from the 1859 Royal Commission on the Defence of the United Kingdom, by convict labour between 1875 and 1885. A narrow gauge railway called the Eastern Defences Railway was built from a pier on the River Medway at Borstal, up the hillside to the fort, and on to Forts Bridgewood, Horsted and Luton to transfer materials and convict labourers to the building sites. Fort Borstal is of polygonal design and was never originally armed. An anti-aircraft battery was based there in the Second World War. It is now in private ownership.
On the edge of Borstal are Rochester and Cookham Wood prisons. Rochester was originally known as Borstal Prison and was founded in 1870. Borstal Prison was once an experimental juvenile prison of the reformatory type set up in 1902. Because it was the first detention centre of its kind in the United Kingdom, the word "Borstal" became synonymous with other detention centres for youths across the country, and elsewhere. In view of that connotation, the prison was renamed 'Rochester Young Offenders Institution'. HM Prison Cookham Wood was added to the site later, in 1978.
