The War Graves Photographic Project
The War Graves Photographic Project original aim was to photograph every war grave, individual memorial, Ministry of Defence grave, and family memorial of serving military personnel from WWI to the present day. However, due to its popularity the project has now extended the remit to cover all nationalities and military conflicts and make these available within a searchable database.
