"Rouen, between Seine and cathedral, uchronic reconstitution of a vanished district" is a project undertaken by "Association Rouen virtuelle". This society was created in 2016 and aims at a virtual 3d reconstitution of the district south of the cathedral, which disappeared during the fire of June 1940, at the beginning of Word War Two. It was a remarkable, historic urban district, full of many heritage houses and buildings.
