A forest of trees at London's Royal Academy

The courtyard of the Royal Academy has been transformed into a grove of trees by the Chinese artist Ai Weiwei. The structures are made from sections of dead trees collected on the mountains of southern China. These were pieced together at Ai’s studio in Beijing to create the eight ‘complete’ trees on show. They’ve been interpreted as a commentary on the way diverse people have been brought together to form ‘One China’.

Viewing the trees is free, but there is a charge for the rest of the Ai Weiwei exhibition which is inside the Academy and continues until December 3, 2015.
