The Blue Skies Project displays 1,078 photos of the sky above the last known location of every former Nazi concentration camp. They have been taken by Belgian artist Anton Kusters and will be accompanied by an audio work by Ruben Samama. They track 13 years in real time from the date of the opening of the first camp to the closure of the last. This is the first time that this installation has been displayed in the capital and will coincide with Photo London.
