Lincolnshire Voices from the Great War will open at Lincoln Castle on Saturday May 28.
Housed in the Victorian Prison, the exhibition will focus on the Battle of the Somme, which this year marks its 100th anniversary.
Coun Nick Worth, Executive Member for Culture and Heritage at Lincolnshire County Council, said: “July 1 will mark the 100th anniversary of the beginning of the Battle of the Somme. Seven Lincolnshire battalions fought there and this exhibition will help ensure their sacrifice, and that of people back home, is not forgotten.
“It would be impossible to tell the whole history of the First World War, so we’ve decided to use personal stories of Lincolnshire people to illuminate little known areas and to bring them alive.
“One of the highlights is a transcription of the diary of a soldier from the local area who records his experiences of the Somme battlefield.
“We’re also sharing the little-known story of the munitionettes, women who went to work in the factories of Gainsborough, Grantham, Grimsby and Lincoln to make tanks, aircraft and munitions.
“In addition, we explore the experiences of a young Lincolnshire tank driver, and Sir William Tritton, its inventor, who in 1919 had the galling experience of assorted civil servants laying claim to having invented the tank.
“Our stories may be from terrible times, but the voices of real people will shine through in deeply recognisable way.”
The exhibition will be on show until September 4.
