Bois-Guillaume is a commune in the Seine-Maritime department in the Haute-Normandie region in northern France. 1 January 2012, it was said to become part of the new commune of Bois-Guillaume-Bihorel but the merger of the two communes has been cancelled in January 2014.GeographyThe town is a wealthy, residential hilltop suburb of Rouen, semi-rural, semi-suburban with a little farming and some light industry. It is considered part of Greater Rouen, being just 3mi to the northeast, at the junction of the D43 and the D928 roads.HistoryBois-Guillaume was originally a Gallo-Roman settlement of which few traces remain. In 1040, William the Conqueror's mother built a country house on the hill; the area thus came to be known variously as Boscum Guillelmi or Bosco Willelmi, later becoming Bois-Guillaume.By 1892, the town was large enough to split into two, thus creating the neighboring commune of Bihorel.On 1 January 2012, the communes Bihorel and Bois-Guillaume started to merge into the new commune of Bois-Guillaume-Bihorel, but this was cancelled in January 2014.ActivitiesBois-Guillaume is well known for its tranquility. No bars are open at night time - people used to go out in Rouen (city center). You can have fun in several parks, it's a nice place for young and adults people to relax. Some soccer pitches are also opened for public (and for free). During sunny days, young people meet up there to play some random games.
