Hosted by the Norman historian Paul Le Trévier, author and editor specializing in Allied bombing on Rouen and World War II in Normandy For the past twelve years, Paul le Trévier has been surveying several times a week the lawn of the St-Sever military cemetery in Rouen. It is the largest British necropolis in France (6.5 hectares). Paul Le Trévier has become THE specialist of this place little known to the general public to which he has dedicated a reference work entitled «Le Jardin aux 12 000 pierres». According to him, this cemetery constitutes a map of the First World War in the open air: soldiers of 20 different nationalities are buried there. The victims come from the four corners of the British Empire of the time: Candians, Australians, New Zealanders, South Africans, nationals of the West Indies (West Indies), Chinese, Poles, Russians... Behind the 11,000 steles that make up the cemetery and its extension, lie some heartbreaking stories that Paul Le Trévier will be pleased to share with you.
