Lumiere, the UK's largest light festival, took place in Durham for the fourth time from 12-15 November 2015.
More than 200,000 visitors saw 29 stunning light installations over four spectacular evenings in Durham City, including a whale in the River Wear, a ghostly fog beneath Durham Cathedral, and 250 locals storming the 50 metre-high arches of Durham Viaduct.
Mysticète, Catherine Garret's extraordinary 3D whale in the river, was a firm festival favourite, as was the World Machine, where the story of the birth of modern cosmology from the 12th Century until the present day was told in this stunning son et lumiere on the façade of Durham Cathedral
Crowds also gathered to play with Cloud, a suitably topical raincloud made up of thousands of bulbs, and 1.26 Durham, the floating aerial sculpture that changed colour according to audience responses to questions via an interactive app. There were also floating fish in the city's market place, and so much more.
We hope to see Lumiere back to Durham in 2017.
The festival is produced by Artichoke and commissioned by Durham County Council with additional support from Arts Council England and a raft of sponsors. For more information visit the Lumiere website.
