Eight and a half miles northeast of Paris is the suburb of Aulnay-Sous-Bois, which, though a commune in its own right, is also a commuter area for people working in France's capital city. Archaeological remains dating back 8,000 years have been found in the area. During the Middle Ages, two communities, Parc and Vieux Pays, developed in the area. The coming of the railway in 1875 brought growth and prosperity, and after the two communities at last settled their differences and came together, Aulnay-Sous-Bois was recognized in 1903. The building of residential homes continued apace through the early 20th century to accommodate those coming to work in the developing chemical and engineering sectors. Today, the cosmetics giant l'Oreal has a large base in the area, although the largest employer by far is PSA Peugeot Citroen. The local railway station is on the Mainline from Paris to Soissons.
