A replica trench is in place at Warminster Civic Centre commemorating the town’s involvement in the First World War.
The trench display features old photographs, newspaper cuttings and artefacts.
It has been put together by an organisation called Wiltshire Soldiers, which has a database of 12,000 servicemen who served during the conflict, and focuses on the Warminster men who were in the battle.
It launched last Thursday and will be in place until 1pm tomorrow.
The exhibition is part of Warminster Town Coun-cil’s programme of events marking the First World War centenary with activities running over the next four years.
Warminster town clerk Heather Abernethie said: “This is all based on information on Warminster and surrounding villages.
“I think the exhibition is absolutely fantastic.”
The exhibition homes a gas chamber and field hospital. It has low roofs, little light and fake rats to give a flavour of what a First World War trench was like.
Historian and author Richard Broadhead, who runs Wiltshire Soldiers, said: “This shows the input of Warminster and the villages around it as well as telling the story of why we went to war.”
Mr Broadhead has organised exhibitions in Swindon, Trowbridge and Calne so far this year.
Volunteers are helping to guide visitors around the Warminster Civic Centre attraction.
Guide Jean Holden said: “The Great War doesn’t feel that long ago as I grew up with my parents who had memories of it.”
