Historical photographs of China
A project to digitise hundreds of photographs documenting China's turbulent history is currently underway at the University of Bristol and is the subject of a BBC Radio 4 documentary on 11 July.
Mostly taken by foreigners living in or visiting China, who took them out of the country to safety, the photographs provide a historical vision of China which is both unfamiliar and fascinating to its citizens now.
You can find out more about the project, and view more photographs, at the Historical Photographs of China website.
Old Photographs Fever - The Search for China's Pictured Past airs on Radio 4 on 11 July at 11am
