A FREE exhibition documenting the award-winning We're here because we're here memorial project is being held at Salisbury Playhouse.

We're here because we're here and saw 1,400 volunteers dressed as soldiers in full First World War uniform pop up in town centres and various locations across the UK, including Salisbury on July 1, 2016.

It was in commemoration of the Battle of the Somme.

The soldiers did not speak but at points throughout the day would sing ‘we’re here because we’re here’ which was sung in the trenches in the First World War.

Each participant represented a soldier who was killed on the first day of the Battle of the Somme. Participants handed out cards to passers-by with the name and regiment of the soldier they represented and, where known, the age of the soldier when he died on July 1, 1916.

Commissioned by 14-18 NOW, the UK’s arts programme for the First World War centenary, the work was created by Turner Prize-winning artist Jeremy Deller in collaboration with Rufus Norris, the director of the National Theatre.

The memorial was produced by Birmingham Repertory Theatre, the National Theatre and 23 regional theatres, including Salisbury Playhouse.

We're here because we're here beat off competition from 1,300 entries to win the title of UK's Best Heritage project in the National Lottery Awards.

The exhibition documenting the day-long work will be staged in the upstairs foyer areas of the Playhouse from Wednesday, October 4 to Thursday, October 26.
