Background
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.
