Ouvrage Oberheid, Military fortification in Cattenom, France

Ouvrage Oberheid is a military fortification in Cattenom centered on a concrete block with two firing chambers and a machine gun turret at the top. The installation includes quarters for roughly 78 soldiers and 2 officers, along with two generators providing the site with power.

The structure was built in 1930 as part of the Maginot Line defensive system along the border. Despite daily bombardments during the June 1940 battles, it sustained only minimal damage.

The site is managed by the association "Ligne Maginot de Cattenom et environs", as are the other ouvrages in the Cattenom Forest. A private individual maintained it in good condition until the 1980s; after that upkeep stopped, the site was gradually looted and vandalised, and the Army, wishing to take the site back, filled in the facades and entrances. The name Oberheid comes from the locality on the salient of the Cattenom Forest where the block stands.

The site is sealed: entrances and facades were backfilled by the French Army, which still owns Oberheid, so the interior cannot be entered. The structure stands in the Cattenom Forest on a salient between Kobenbusch and Galgenberg, reached on foot through the woods. The association Ligne Maginot de Cattenom et environs manages the ouvrages of the forest.

One of the four GFM cloches served as an observation post tactically attached to the gros ouvrage de Métrich, not to Oberheid's own command. The site stayed French Army property and was maintained by a private individual until the 1980s, before looting and vandalism led to the entrances being backfilled. It is now managed by the association Ligne Maginot de Cattenom et environs.
