This fort was completed in 1914, after the outbreak of the First World War, using the banks of the former earthwork. It was designed on a pentagon plan. In the "neck" to the left from the axis there were brracks, and on the right an ammunition store. In the enceinte infantry was positioned, protected by a stone parapet. Behind them in the "head" and "shoulders" separated with traverses there were artillery positions. The moat was defended from two caponiers.
