Description
In 1873, the decision was made to set up a simple entrenched post on the Gros Cerveau massif, armed with long-range artillery pieces.
In 1890, two fortified structures were built: the Pointe de la Pointe and the Gros Cerveau. These buildings have a similar architectural organization, with the following artillery positions: 4 155 mm long guns, 4 120 mm guns, 4 95 mm guns and 2 mortars.
Equipped with a light enclosure preceded by a ditch, the gun emplacements, cut directly into the rock, are connected by underground galleries. The barracks are equipped with rainwater tanks that can hold 160 m3.
The Big Brain structure received a garrison of 250 men from the 2nd Battalion of the 115th Territorial Infantry Regiment and 260 men from the 7th Battery and the 13th Artillery Foot Battery. The two barracks of the Pointe de la Pointe structure were capable of accommodating 1 officer and 108 men each.
