The City of London suffered huge loss of life at the Battle of the Somme, which started on 1 July 1916, and is regarded as the day that changed British history.
Now, an exhibition of evocative photographs by Michael St Maur Sheil showing the battlefields as they are today, alongside archive pictures from 100 years ago, will take place in east London.
Fields of Battle, Lands of Peace will include large photos by St Maur Sheil, on display at Guildhall Yard. It's free to see.
This exhibition follows a hugely successful one in St James's Park in 2014, which was seen by an estimated 4.7 million visitors between August and November.
The exhibition will be accompanied by a series of lectures, including talks given by Michael St Maur Sheil and Sir Anthony Seldon, and Somme artefacts displayed in the City of London Heritage Gallery at Guildhall Art Gallery.
Fields of Battle, Lands of Peace: Somme 1916, 1 June-5 July, Guildhall Yard, free.
