, a location that would be untenable in combat. This would have profound effects on the forts' ability to endure a long assault. The service areas were placed directly opposite the barracks, which opened into the ditch in the rear of the fort (i.e., in the face towards Liège), with lesser protection than the two "salient" sides. The Brialmont forts placed a weaker side to the rear to allow for recapture by Belgian forces from the rear, and located the barracks and support facilities on this side, using the rear ditch for light and ventilation of living spaces. In combat heavy shellfire made the rear ditch untenable, and German forces were able to get between the forts and attack them from the rear. The Brialmont forts were designed to be protected from shellfire equaling their heaviest guns: 21 cm. The top of the central massif used of unreinforced concrete, while the caserne walls, judged to be less exposed, used . Under fire, the forts were damaged by 21 cm fire and could not withstand heavier artillery.

Armament

Lantin's armament included two double 15 cm gun turrets, two double 12 cm gun turrets and 57 mm gun turrets. It also mounted an observation turret with a searchlight. Rapid-fire 57 mm guns were provided in casemates for the defense of the ditches and the postern. The large weapons were all German products, made by

First World War

In 1914 the Fort de Lantin was one of the last Liège forts to suffer German bombardment. Liège first came under attack on 6 August 1914. When the Liège proved unexpectedly stubborn, the Germans brought heavy siege artillery to bombard the forts with shells far larger than they were designed to resist. Lantin was heavily bombarded starting 10 August. It surrendered the next day, due to the asphyxiating atmosphere within.Donnell, p. 48-49

Lantin was not upgraded in the 1930s as part of the

, remaining essentially as it was built by Brialmont. The fort was acquired by the preservation organization ''Les Amis du Fort de Lantin'' from the Ministry of Defense in 1983, and is open for public tours at stated times.
