Letters and photos documenting the Hull prison riot of 1976 will be part of an upcoming exhibition.
The protest against alleged staff brutality involved about 100 prisoners destroying their cells, smashing doors and furniture, and throwing slates at passers-by.
Within These Walls, which will be in the old governor’s house as part of Heritage Open Days, will include the general history of the site, including prisoners’ death certificates, artwork and smuggled weaponry.
The prison report from governors, as well as newspaper clippings, photos and documents from before, during and after the riot, will be on display in the exhibition, which runs from 10:00 until 14:00 BST on 16 and 17 September.
Following the 1976 riot, Hull prison was out of use for a year and the cost of repairing the damage was estimated to be up to £4m.
The story behind the trial and execution of a woman who died at the prison after murdering her husband will also be on display.
Ethel Major, a middle-aged Lincolnshire housewife from the 1930s, was hanged after being found guilty of poisoning her husband with sandwiches full of strychnine.
