World War One: 'Lights Out' vigils held
- 5 August 2014
- From the section Northern Ireland
Lights have been switched off for one hour across Northern Ireland to commemorate the outbreak of World War One.
The memorial, which took place between 22:00 and 23:00 BST on Monday, was inspired by the words of the Foreign Secretary at the time.
Sir Edward Grey said: "The lamps are going out all over Europe; we shall not see them lit again in our life-time".
Nearly 50,000 Irish-born soldiers are known to have died in World War One.
Historians have estimated that more than 200,000 served in the British Army and Navy from 1914 to 1918.
