HM Prison Shepton Mallet

HMP Shepton Mallet, sometimes known as Cornhill, is a former prison in Shepton Mallet, Somerset, England. When it closed in 2013, it had been the United Kingdom's oldest operating prison, following the closure of HMP Lancaster Castle in 2011. Before closure, Shepton Mallet was a category C lifer prison holding 189 prisoners. The prison building is Grade II* listed, while the former gatehouse and perimeter walls are Grade II.

The prison was opened before 1625 but was already in poor repair by the end of the First English Civil War in 1646. It was expanded in 1790 but conditions were again criticised in a report of 1822 and further building work was undertaken in the 1820s and 1830s. This included the installation of a treadwheel for those sentenced to hard labour. In 1843 the number of cells was increased by adding a second storey to each wing. The prison was damaged during a fire in 1904. In 1930 the number of inmates had fallen and the prison was closed.

Following the outbreak of the Second World War in 1939, the prison was reopened as a military prison. It was initially used by the British Army and later by American forces who constructed a new execution block to hang condemned prisoners. It was also used for the storage of important historical documents from the Public Record Office in London, including Domesday Book. Following the war the prison continued as a military "glasshouse" until it was returned to civilian use in 1966.

The prison was decommissioned in 2013 and now serves as a tourist attraction, with guided tours and other activities.

17th and 18th centuries
The prison was established as a house of correction in 1625 to comply with the 1610 Bridewell Act of King James I requiring that every county have such a house. The building and surrounding land of 1 acre was bought from the Reverend Edward Barnard for £160. In the 17th century Shepton Mallet was not the only place of imprisonment in Somerset: the County Gaol was in Ilchester; there was another house of correction at Ilchester; and one at Taunton.

At the time all prisoners – men, women and children – were held together in reportedly dreadful conditions. The gaoler was not paid, instead making an income from fees from his prisoners; for example, for providing them with liquor. By the end of the First English Civil War in 1646 the house of correction was described as being in poor repair. During the Bloody Assizes following the Monmouth Rebellion at least 12 local men were held at the gaol before being hanged, drawn and quartered at the Market Cross.

In 1773, a commissioner appointed by Parliament to inspect prisons around the country reported that sanitation at Shepton Mallet House of Correction was extremely poor. He said:

"Many who went in healthy are in a few months changed to emaciated, dejected objects. Some are seen pining under diseases, expiring on the floors, in loathsome cells, of pestilential fevers, and the confluent smallpox. Victims, I will not say to cruelty, but I must say to the inattention of the Sheriffs, and Gentlemen in the commission of peace. The cause of this distress is, that many prisons are scantily supplied, and some almost totally unprovided with the necessaries of life."

- John Howard's report to Parliament

In 1790 additional land was purchased to extend the prison, and around this time men and women began to be held in separate areas. Further extensions were carried out from 1817 to 1822, with the prison holding about 200 prisoners.

19th century


A report into the state of prisons in Somerset by Sir John Hippisley of Ston Easton Park in 1822 criticised the conditions in which prisoners were held. He proposed a five-year plan to expand the prison at a cost of £5,000.

In 1823, a large treadwheel, designed by William Cubitt and built by Stotherts of Bath, later Stothert & Pitt, was installed within the prison, in the 1840s Stotherts were contracted as engineers to build the new Bath City Gaol in Twerton, and later went on to build the treadwheel at that prison. The building for the treadwheel and other new buildings were designed by George Allen Underwood. Men who had been sentenced to hard labour would serve their punishment on this. 40 men would tread the wheel for many hours at a time, a punishment which was recorded as causing hernias in some convicts. The wheel was used to power a grain mill situated outside the prison wall. The wheel remained in use until 1890. Other prisoners were engaged in breaking stones which were used for roadbuilding, oakum picking (unpicking old ropes) and other tasks.

Further building work to designs by Richard Carver, the county surveyor, was undertaken in the 1830s and 1840s. This included the rebuilding of the front range and the addition of the gatehouse. The chapel was built in 1840. The wings were adapted and a second storey added to each one. Additional building work completed the enclosure of the quadrangle or exercise yard.

In 1842 inspectors appointed by the government reported that Shepton Mallet prison was:

"in greatest want of new cells for the purpose of dividing the prisoners from each other ... In number 11 of Ward 8, no less than eight men have slept in the same room in company from January to September, 1841, although in this very room there are only six bedsteads. Boards are brought in and placed on the floor when the bedsteads are not sufficiently numerous."

- Report of Her Majesty's Inspectorate

Ilchester Gaol closed in 1843, with the inmates being transferred to Shepton Mallet and Taunton. In 1845 the prison was recorded as holding 270 prisoners. By 1897 the population was only 61, overseen by a governor, three warders, six assistant warders and a night watchman. Other staff included a chaplain and assistant chaplain, a surgeon, a matron and a school master. In 1884 it was designated as the county gaol for Somerset under the Prison Act 1877.

The Bristol "baby farmer", 1879
Notorious Bristol "baby farmer" Amelia Dyer spent six months at Shepton Mallet Prison. Her trial was held at Long Ashton on 29 August 1879, and two newspapers report the summing-up of the judge, stating that she would reflect on her actions behind the walls of Shepton Mallet Gaol, for the period of six months under hard labour. Although the court was close to the centre of Bristol, it was within the jurisdiction of Somerset, hence her time at Shepton Mallet as opposed to Bristol Prison. She was charged with failing to have the necessary permissions or licence for the maintenance of children, and for attempted suicide. She was acquitted on the latter charge.

1904 fire


At 10:15pm on Saturday 2 July 1904 a fire, believed to have been started by a prisoner about half an hour earlier, was discovered in C block. The alarm was raised by the ringing of the prison bell and the prisoners were evacuated to the prison chapel. Within ten minutes the town fire brigade, which was provided by the Anglo-Bavarian Brewery, was in attendance. They were joined at about midnight by the Wells brigade and at about 3:00am by the Frome and Glastonbury brigades. The fire had spread quickly within C block and was fought by prisoners, warders and firemen working together; prisoners helped to man the hoses and worked the fire engine pumps in shifts.

Despite the opportunity offered by the disruption, no prisoner attempted to escape. There were no fatalities as a result of the fire, and no major injuries. Whilst contemporary photographs show that the roof of C block was substantially destroyed, the building itself, being constructed of stone and concrete, remained nearly intact. Consequently it was not necessary to transfer any prisoners to other jails.

Closure in 1930
In 1930 the Prisoner Commissioners recommended to the Government that Shepton Mallet Prison should be closed because it was under-used, having an average population in previous years of only 51 inmates. The prison closed in September of that year, with the prisoners and some of the staff transferring to other jails in neighbouring counties. The prison remained empty except for a caretaker until the outbreak of the Second World War.

Civilian executions


The total number of executions at Shepton Mallet in its early years is unknown. Seven judicial executions took place within the prison walls between 1889 and 1926:
 * Samuel Rylands (or Reylands), aged 23, was hanged on 13 March 1889. He was convicted at the Assize Courts in Taunton, Somerset on 20February 1889 for battering to death 10-year-old Emma Jane Davies at Yeabridge, Somerset on 2January 1889.
 * Henry (Harry) Dainton, aged 35, was hanged on 15December 1891 by hangman James Billington. He was convicted for drowning his wife in the River Avon.
 * Charles Squires, aged 28, was hanged on 10August 1893 by James Billington. He was convicted at the Assize Courts in Wells, Somerset for smothering to death his wife's two-year-old illegitimate son.
 * Henry Quartly (or Quartley), aged 55, was hanged on 10November 1914 by hangmen Thomas Pierrepoint and George Brown. He was convicted at the Assize Courts in Taunton, Somerset on 20October 1914 for fatally shooting 59-year-old Henry Pugsley at Parson Street, Porlock, Somerset on 3June 1914.
 * Verney Asser, a 30-year-old Australian soldier of the 2nd Training Battalion, was hanged on 5March 1918 by John Ellis and William Willis. He was convicted at the Assize Courts in Devizes, Wiltshire on 16January 1918 for fatally shooting his roommate 24-year-old Corporal Joseph Harold Durkin at Sutton Veny Camp on Salisbury Plain, Wiltshire on 27November 1917.
 * William Grover Bignell, aged 32, was hanged on 24 February 1925 by Thomas Pierrepoint and Robert Baxter. He was convicted at the Assize Courts in Devizes, Wiltshire on 20 January 1925 for fatally cutting the throat of his 37-year-old girlfriend Margaret Legg in a field near Tetbury, Gloucestershire on 25 October 1924.
 * John Lincoln (a.k.a. Ignatius Emanuel Napthali Trebich Lincoln), aged 23, was hanged on 2March 1926 by Thomas Pierrepoint and Lionel Mann. He was convicted at the Assize Courts in Devizes, Wiltshire on 21January 1926 for fatally shooting 25-year-old Edward Richards at Victoria Avenue, Trowbridge, Wiltshire on 24December 1925.

Their remains were buried in unmarked graves within the walls of the prison, as was customary following British executions.

Use during the Second World War
The prison was reopened for British military use in October 1939. It soon housed 300 men from all three armed services, with some having to live in huts in the prison yard.

In November 1940 three British soldiers, who were incarcerated in room 142 close to the B1 landing died of asphyxiation/carbon monoxide poisoning. Another soldier, also held in the same room survived. The names of the soldiers who died were Frank Girvan (of Fife), Glen Roy Williams (Bridgend) and Harold Smith (Manchester).

Public Records storage
With the outbreak of war the prison also took into protective storage many important historical documents from the Public Record Office in London, including the Domesday Book, the logbooks of HMS Victory, the Olive Branch Petition (1775), and dispatches from the Battle of Waterloo. In all about 300 tons of records were transported to Shepton Mallet. Some documents, but not Domesday Book, were moved out of Shepton Mallet on 5July 1942 due to concern at the concentration of important items being held in one place, especially with German bombs falling on nearby Bath and Bristol. During their time at Shepton Mallet the archives were still able to be accessed. The archives were returned to London after the end of the war, between 10July 1945 and 1February 1946.

American military use


Between mid-1942 and September 1945 the prison was used by the American military as the "6833rd Guardhouse Overhead Detachment", later "The Headquarters 2912th Disciplinary Training Center – APO 508 United States Army". The prison was entirely staffed by American military personnel during this period. The first commandant was Lieutenant Colonel James P. Smith of the 707th Military Police Battalion.

At times during its use by the Americans Shepton Mallet held many more men than it had before. At the end of 1944 there were 768 soldiers imprisoned, guarded by 12 officers and 82 enlisted men.

American military executions
Under the provisions of the United States of America (Visiting Forces) Act 1942, 18 American servicemen were executed at the prison: sixteen were hanged in the execution block and two were shot by a firing squad in the prison yard. Three of the hangings were double executions, i.e. two condemned prisoners stood together on the gallows and were executed simultaneously when the trap-door opened.

Of the 18 men executed, eight were convicted of murder, six of rape (which had not been a capital offence in the United Kingdom since 1841), and four of both crimes. A Channel 4 film claimed that a disproportionate number of black soldiers were executed. Although the U.S. military was 90% white, 10 of the 18 men executed there were black and three were Hispanic.

The Americans constructed a small, two-storey building containing a gallows (of identical design to those used in British prisons) adjoining one of the prison wings. The flat-roofed execution block has a single window, approximately one metre above the trap-door. There is an external wooden door on the ground floor which gives access to the area underneath the trapdoor. It was through this door that the bodies of executed prisoners were removed. The barred steel mortuary door, located below C wing, directly faces the external wooden door to the execution block. The execution block is sandwiched tightly between two much larger buildings, close to the rear of the prison. Visually, it clashes with the other architecture because it is made of red brick, whereas the rest of the prison is constructed from stone.

The executioner at most of the hangings was Thomas William Pierrepoint, assisted mainly by his more-famous nephew Albert Pierrepoint, though some other assistant executioners were used, e.g. Alex Riley and Herbert Morris. Executions by hanging took place after midnight, at around 1:00am. Albert Pierrepoint is known to have disapproved of the Americans' practice of reading out to the condemned man as he stood on the trap-door the details of his offence and sentence, then allowing him to make a final statement. He said:

"The part of the routine which I found it hardest to acclimatise myself to was the, to me, sickening interval between my introduction to the prisoner and his death. Under British custom I was working to the sort of timing where the drop fell between eight and twenty seconds after I had entered the condemned's cell. Under the American system, after I had pinioned the prisoner, he had to stand on the drop for perhaps six minutes while his charge sheet was read out, sentence spelt out, and he was asked if he had anything to say, and after that I was instructed to get on with the job."

Initially, the remains of American prisoners executed at Shepton Mallet were interred in unmarked graves at "Plot X" in Brookwood Cemetery, Surrey. Plot X was located in a distant corner of the cemetery, away from the other plots and adjacent to tool sheds and a compost heap. Executed prisoners interred there were not given coffins, but were put into cotton mattress covers and buried in individual graves under numbered markers. Plot X had room for one hundred graves and was the first effort to segregate executed Army prisoners from those who had been killed in combat.

In 1949, all eighteen bodies were exhumed. The remains of David Cobb were repatriated to his home of Dothan, Alabama. The remaining 17 were reburied in Plot E at Oise-Aisne American Cemetery and Memorial in France. Plot E is a private section intended for the "dishonoured dead" which is situated across the road from the main cemetery. Visits to Plot E are not encouraged. Public access is difficult because the area is concealed, surrounded by bushes, and is closed to visitors. In any case, all the grave markers in Plot E bear only numbers (not names), which makes identification of individual soldiers impossible without the key. The US government published a list identifying the occupants of each grave in 2009.

British military use
In September 1945 the prison was once again taken over by the British Army and became a British military prison ("glasshouse") for service personnel. It was used for soldiers who were going to be discharged after serving their sentence, provided that sentences were less than two years. (If more than two years, the sentence was served in a civilian prison.)

Amongst the soldiers held here were the Kray twins who, while serving out their national service in the gaol after absconding, met Charlie Richardson. Discipline was very strict and the punishments meted out to prisoners were reportedly extremely severe. On 10March 1959 a riot (officially termed a mutiny) began in the dining hall. Thirteen soldiers were subsequently tried by court martial, and five were sentenced to three years' imprisonment; the remainder were acquitted.

Postwar use
The prison was returned to civilian use in 1966. It was initially used to house prisoners who, for their own protection, could not be housed with 'run-of-the-mill' prisoners, and also for well-behaved first offenders.

The gallows in the execution block was removed in 1967 and the room became the prison library. A new kitchen, boiler room, chapel and education block was added.

In 1973, Shepton Mallet became a training prison for men serving sentences of less than four years. The aim was to provide the inmates with the education and skills necessary for them to become productive members of society after their release. There were now about 260 prisoners who worked in a range of workshops, including plastic moulding, tailoring and scrap metal recovery. Some also worked outside the prison (some unsupervised), for example in the local park or churchyard, on local farms or at the Babycham cider mill.

In the 1980s the prison held prisoners who had been in prison several times before and had not reformed. Around this time the population continued to be 260 living in accommodation designed for 169. In 1991, Shepton Mallet took its first category 'C' life prisoners – those nearing the end of their sentences. The maximum number of prisoners to be held in the prison was fixed at 211.

In 1992, the Chief Inspector of Prisons, Judge Stephen Tumim, issued a report which said:

"We doubt that Shepton Mallet Prison has a future in its present role and are aware that the total population could be absorbed into vacancies at other category 'C' establishments in the area. If the prison is to continue it requires a clear function or set of functions which match the physical resources."

- HM Chief Inspector of Prisons

Shepton Mallet became the first category 'C' second-stage solely-lifer prison on 1August 2001. It had an official capacity of 165, but in June 2010 was holding 188 prisoners, with arriving prisoners having to share cells for up to a year. It was divided into four wings:
 * A wing – 37 spaces
 * B wing – 94 spaces
 * C wing – 43 spaces
 * D wing – 15 spaces

An inspection report on the prison was issued following a full announced visit by inspectors from HM Chief Inspector of Prisons carried out in June 2010. The introduction to the report states:

"This very positive report ... is testament to the benefits that can flow from having a small-scale niche prison with a settled population. Despite its ageing physical environment, the prison was a very safe place, with positive staff-prisoner relationships, a reasonable amount of activities, and a strong focus on addressing the serious risks posed by the population."

- HM Chief Inspector of Prisons

The report commented in particular on the very good relations between prisoners and prison officers, and the low levels of self-harm, bullying, violence or drug use. Whilst the inspectors said that the accommodation was "old and tired", they felt that it was adequate for the current number of prisoners. The inspectors were concerned by proposals to increase the population by 70 prisoners.

Closure
On 10 January 2013, Justice Secretary Chris Grayling announced that Shepton Mallet Prison was one of seven prisons in England to close. HMP Shepton Mallet closed on 28March 2013. The closure ceremony was attended by officers and staff, past and present, the Bishop of Bath and Wells, veterans and serving personnel of MTC Colchester, representatives of the US Armed Forces and family and friends. The final act was the handover of the union flag to the last governor. The event was also marked by a flypast of a Royal Naval Lynx helicopter from RNAS Yeovilton and an hour and a half peal from the local church bells. The staff, who marched to parade just inside the main gates, accompanied by the RNAS Yeovilton Volunteer Band, were then dismissed.

Sale and tourist attraction
After closure, the prison was put up for sale by the Ministry of Justice. The original deadline to declare a preferred bidder for the site was the end of March 2014 but this was put back until mid-August. Proposals for the site included converting it into prison heritage centre with hotel, bar and restaurants as well as housing, or converting the complex into a museum, gym, a hotel and ghost and horror tours. The proposals were rejected in October.

In December 2014, it was agreed Shepton Mallet Prison – along with Dorchester Prison, Gloucester Prison and Kingston Prison – would be sold to City and Country. It is now open to the public as a historical tourism destination, offering guided tours, ghost tours and a variety of other activities. In 2021, plans were approved to turn part of the prison into accommodation.

Near closure as a tourist attraction
On 28 November 2023, it was announced on the prison's social media channels that the prison would close its doors as a tourist attraction on 2 January 2024 following a breakdown in relationship between the owners, City & Country, and the prison's operators, Cove Group, who also operate Shrewsbury Prison in Shropshire.

On 21 December 2023, Cove Group announced that the closure had been cancelled after last-minute negotiations with City & Country, that the prison would continue to be open to the public through the New Year, and that further negotiations were planned to take place on the New Year.

As of January 2024, Shepton Mallet Prison continues to be open to the public, and is offering annual visit passes, implying that the prison will continue to be open in the foreseeable future.
