The skyline of Durham has being turned into an illuminated work of art as part of a four-day festival of light.
Artworks by more than 30 artists have been scattered across the city since as part of Lumiere 2011.
The festival started in 2009 and last year more than 75,000 people came to the city over three nights. Fiona Trott reports.
