Kent tonight commemorated the centenary of the day Britain entered World War One as the lights went out across the county.

Thousands of people took part in the nationwide Lights Out event at 10pm at the end of an emotional day of tributes.

Nowhere was the occasion more poignant than in Folkestone, where earlier Prince Harry had officially opened the new Memorial Arch at the top of The Leas.

Hundreds of people gathered at the site as lights flickered out across the town and the new arch lit up the night sky.

And at the nearby Shorncliffe Military Cemetery the Shorncliffe Trust placed hundreds of lanterns on the graves of the fallen at 11pm.

The Light's Out event was organised by 14-18 NOW, the official cultural programme for the First World War Centenary. Supported by the Royal British Legion, it was inspired by the words of wartime Foreign Secretary Sir Edward Grey, who said on the eve of WW1: "The lamps are going out all over Europe; we shall not see them lit again in our lifetime."

Earlier a parade of 1,000 military personnel led by the Band of the Brigade of Gurkhas and civilians behind the Folkestone Pipers and Drummers marched along The Leas from The Grand to the new arch ahead of a short commemoration service with Prince Harry laying a wreath at the war memorial.

He then took the salute before joining the parade down the Road of Remembrance to the harbour - a route which millions of men took before departing from Folkestone harbour on their way to the Western Front - meeting members of the public and chatting to spectators.

Readers have been sharing their photos of their own tributes, and a selection are below.
