Lights across Britain were switched off for an hour on Monday night in a tribute to the dead of World War One inspired by the prophetic observation of Britain's foreign minister on the eve of war 100 years ago.
A monumental pillar of light created by Japanese artist Ryoji Ikeda was beamed into the clouds over London, acting as beacon for the capital. The installation will fade away as the sun rises over the city on Aug. 11.
