In the latter year, the Mare River, which had until then been to the west of Villemagne, then changed its course cutting the town in two; the part of the town to the left (East) of the new course was severely damaged and was abandoned including its ancient church of St. Sauveur. The part of the town on the new right bank, which corresponds to the current historic centre of Villemagne, was covered with 1.80 m of water; when the water receded the town was partially buried under a deep layer of silt. Numerous further floods resulted in the village being raised by up to 3 metres in some places.
