The territory of Le Gua is ideally located at the crossroads of two major axes: La Rochelle, Royan and Oléron Saintes. This, linked to the remoteness from major urban centers enabled the town to retain a good business in his town and its outskirts with specialized shops. The town is so today one of the economic centers of the area. The town has the originality to have several living centers. The villages of Chalons, Souhe, Saint Martin du Gua, and Monsanson Dercie gather almost half of the inhabitants. As elsewhere, especially residential villages became. Yet it was not so long ago, there was everything one needs. Saint Martin, for example, had before the war, three cafes, a mechanic, a bakery, two grocery stores, and it was still possible to have their hair done or buy hardware.
