Bertrand Cavalier investigates how political upheaval becomes visible in the urban landscape and how this affects the lives of the people who live in it. He photographs places that have been marked by armed conflicts in the past. For inhabitants, this is often no more than the backdrop against which they live their lives. However, politics have a way of subliminally impacting on people's habits and dictating behaviour. By photographing the townspeople in their own context, Cavalier reveals their true connection with their environment. The cities photographed include Belfast and Sarajevo, where the wounds caused by armed conflict and war are still fairly fresh. The title suggests that concrete, unlike wood or paper, resists fire - but it does not resist history.
