Formerly the first post house coming from Paris, also known for the legend of Christ who stood at the crossroads of the seven roads, this town is located in the center of the plateau that bears its name.
It is now turned towards the future: capital of high technology, it is careful to preserve its heritage and its agricultural vocation. Large-scale farms, covering an area of 985 hectares, are assigned to the cultivation of cereals to take advantage of one of the most fertile lands in Europe. A farm in the town is home to one of the largest cattle herds in France, and is available for free picking of flowers, vegetables and fruit.
The site of the ponds - the old pond, ornithological reserve, and the new pond, conducive to the development of sailboats - is marked by the CEN (Center for Nuclear Studies, 200 hectares, including 96 in the town) and the CEPr (Thruster test center, 100 hectares). It splits the village into two parts: the Val d'Albian and the old town. A business area is located halfway, its hotel offers a large capacity.
