The Batterie de Bouviers (French pronunciation: [batʁi də buvje]) is located in the commune of Guyancourt, Yvelines, France.

[1] The Batterie du Ravin de Bouviers is of modest dimensions, and is therefore sometimes termed a redoubt.

However, the introduction of high-explosive shells capable of penetrating masonry made these positions obsolete almost as soon as they were completed.

The casemates are covered by soil up to 5 feet (1.5 m) thick in a trapezoidal mass, using material excavated from the battery's dry moat, which surrounds the position.

[1] The gate is crowned with the inscription "Batterie de Bouviers" and "1879," with a relief of a mortar on the keystone.

Rainwater was collected by gutters and channeled to cisterns under the battery, supporting at least 200 troops and 19 artillery pieces.

The forts closest to the frontiers were modified, but the fortifications of Paris received little improvement due to financial restrictions.

From 1933 the battery was leased to Hispano Suiza who surrounded it with numerous industrial buildings, where the company made munitions.

[2] At the beginning of World War II, the battery was bombarded and munitions production was relocated to the Charente.
