Lights, lamps and candles around the county were put out last night to mark the beginning of the First World War.
People all over Leicestershire paid tribute to those who fought and died between 1914 and 1918 by taking part in Light Out events and a number of remembrance ceremonies at county memorials.
In the city, the Dean of Leicester Cathedral, the Very Rev David Monteith led a service and vigil at St Martin's.
One light was left lit between 10pm and 11pm to mark the start of the war.
It was part of a nationwide gesture, called Lights Out, inspired by the words of wartime Foreign Secretary Sir Edward Grey.
Speaking on the eve of the war, he said: "The lamps are going out all over Europe; we shall not see them lit again in our lifetime."
Staff at County Hall, in Glenfield, also mirrored the occasion and left one single light on.
Earlier that day, veterans had also placed personal messages on camouflage netting and watched as balloons were released in memory of the fallen.
