Ouvrage Mauvais-Bois - Design and Construction

Design and Construction

Mauvais-Bois was approved for construction in October 1931. It was completed at a cost of 11 million francs by the contractor Monod of Paris. The initial phase consisted of three combat blocks linked by deep underground galleries. In a second phase, Mauvais-Bois was to be expanded to function as a gros ouvrage, with two additional blocks mounting artillery, as well as remote entrances for munitions and personnel, and a larger network of deep underground galleries. The rise in tensions between France and Germany in the late 1930s prevented this second phase from being pursued.
