LIGHTS OUT Jeremy Deller app for iPhone and iPad

At 11pm on 4 August 1914 Britain declared war on Germany, ushering in one of the darkest periods in our history.

As the moment approached, the British Foreign Secretary Sir Edward Grey made the famous remark: “The lamps are going out all over Europe; we shall not see them lit again in our life-time”.

In a dramatic UK-wide event LIGHTS OUT is an invitation to everyone to turn off their lights from 10pm to 11pm on 4 August, leaving on a single light or candle for this shared moment of reflection.

LIGHTS OUT invites artists to create large-scale, site-specific artworks at locations across the UK. A digital artwork will also be commissioned in response to LIGHTS OUT.

LIGHTS OUT, working closely with the Royal British Legion, will be one of the largest participatory events of its kind ever seen in the UK, and will complement the candlelit vigil held at Westminster Abbey on 4 August.
