HM Prison Lincoln

HM Prison Lincoln is a Category B men's prison in Lincoln, England, operated by His Majesty's Prison Service. It opened in 1872 as a local prison for remand and convicted prisoners, replacing the old prison at Lincoln Castle. The original buildings from 1869–72 are listed as notable examples of High Victorian Gothic design.

Between 1900 and 1961, the prison conducted 18 judicial executions, with the last being Wasyl Gnypiuk in 1961. A significant riot occurred in October 2002 when prisoners seized control of part of the prison after attacking a staff member; it took eight hours to quell.

In March 2003, The Prison Reform Trust reported Lincoln as the most overcrowded prison in England, holding 13 inmates over its capacity. As of April 2023, its operational capacity is 650 inmates.

Today, the prison accommodates adult male remand and convicted prisoners from Lincolnshire, Nottinghamshire, and Yorkshire. It features four residential wings (A, B, C & E), a segregation unit, and offers programs such as production workshops, education, vocational training, and offending behaviour courses. Notable former inmates include Jeffrey Archer, Fenner Brockway, Don Brothwell, John George Haigh, John Poulson, Percy Toplis, Éamon de Valera, and Charles Salvador.

The prison has a rich history marked by significant events, including executions, riots, and overcrowding issues, while continuing to provide various facilities and programs for inmates.
