 The municipality of Pont-à-Celles was created from 6 former seigniories (including Luttre).At the same time, the invaded territories were divided in 9 departments.Some municipalities, including that of the new Pont-à-Celles, were withdrawn from Nivelles (which went to the Dyle department, later which became the province of Brabant in 1815) and became part of the Jemappes (named after a French victory in 1792) department.
