But what difference can writing poetry have on inmates?
It’s one of the questions being asked at London’s Southbank Centre this week.
'Prison Poetries' is a free panel discussion which will share the experiences of ex-offenders.
It’s supported by the Koestler Trust, a prison arts charity, which exhibits and sells work by inmates.
Tim Robertson, chief executive of the Koestler Trust said: ‘’The vast majority of prisoners are going to come out and we need to give them the tools to resettle into society and poetry can go some way to doing that."
