The construction of the fort started in 1856. A year later, a single-storey redoubt built on a square plan was ready, equipped with 9 artillery embrasures and 6 shooting slots for small arms. By 1861, it was surrounded with a wet moat, defensive walls from the north. Some of the field cannon posts were moved to the rampart.
