After an evocation of the Liberation of Saint-Sauveur-le-Vicomte by the American troops on June 16, 1944, a guide will present the program of the Reconstruction of the commune, which had been destroyed at about 60%. Designed by the architect Olivier Lahalle, the town planning plan focused on redesigning the town’s roads, around islets, and redefining public spaces by clearing the surroundings of the castle. Its ancient ditches were occupied before the war by a front of constructions while the building housed a hospice and the Barbey museum of Aurevilly. Beyond the restoration of repairable buildings (including the parish church, with stained glass windows created by Paul Bony, a collaborator of Braque, Chagall and Matisse), the Reconstruction first focused on private housing and businesses. Some are restored intermittently, sometimes in the form of isolated bourgeois houses, removed from the street. But the most numerous are gathered in linear or closed islets, especially on the outskirts of the castle where the architecture is the most careful. It is also necessary to rebuild most of the public buildings: town hall, hospice, gendarmerie, museum, studs, perception... The work of the hospice and the «municipal group» remains the most significant.
