Beyond the Deepening Shadow

Beyond the Deepening Shadow: The Tower Remembers was an artistic installation at the Tower of London in November 2018, to commemorate the First [World War centenary|centenary] of the end of the First World War.
Each evening in the week before Remembrance Day, 10,000 torches were lit in the moat of the tower, after an opening ceremony of a bugle call, minute of silence and reveille. The torches remained lit for several hours while loudspeakers broadcast a soundscape composed by Mira Calix, based on a sonnet written by nurse Mary Borden to a British officer at the Somme. The event was conceived by Tom Piper and directed by Anna Morrissey.
The installation was similar to Blood Swept [Lands and Seas of Red], an installation of poppies at the Tower which commemorated the start of the war. That was so popular that crowd control measures were organised to control the large number of spectators.
