A war memorial marking the centenary of the First World War and designed by inmates at Wiltshire prison has been unveiled.
The four-foot high memorial was carved by stonemasons at Salisbury Cathedral and will sit on a lawn within the visitors' area of the category C HMP Erlestoke.
The badges of the Army, Navy and Royal Air Force have been carved on the monument - with the words land, sea and air inscribed beneath.
A gun with a helmet is on the fourth side of the structure, under the quotation: "Now listen, For a moment, The world is silent, Peace be with you".
All prisoners will pass the war memorial as part of their daily routine.
During a ceremony held at the prison on Tuesday, the Dean of Salisbury, the Very Reverend Nicholas Papadopulos, dedicated the memorial.
He said: "It is very easy to regard prisoners as 'out of sight and out of mind', and to leave the job of rehabilitation to others"
"But we all must take responsibility for the society in which we live, and strive to make it better.
"I am incredibly proud of what has been achieved by the prisoners and our masons working together.
"We must cherish the hard-won rights and freedoms we enjoy today, inside and outside the prison system, whether working together to create something as meaningful as this memorial, or simply taking time to pause and reflect on the sacrifice of others."
Prisons Minister Rory Stewart said: "This memorial is a moving tribute to the fallen soldiers who lost their lives bravely serving our country.
"I am grateful to Salisbury Cathedral for giving offenders from HMP Erlestoke the chance to participate in this hugely worthwhile project.
"Such opportunities provide a true sense of purpose - helping to support rehabilitation and allowing them to give back to society."
The memorial is part of a wider First World War centenary initiative within the prison, which was conceived by the prisoners themselves.
Prisoners also worked to create a magazine of poetry and writings about the First World War.
