This page explains how to find the Maginot Line Forts in Both Northern France and In the South of France, their is at the moment, no information on the Rhine casemates.

The information for the Northern Sites comes from Clayton Donnell's Web site with his permission. I would like to thank Caspar Vermeulen for his help with the Southern forts

Northern Maginot Line Forts Open to the Public

Ouvrage de La Ferté
- Located just off of the N43 which runs from Sedan to Montmédy, about 25 km south of Sedan. Take D52 south out of Blagny, through the village of Villy. The fort is just south of the village. Open Sunday afternoons, Palm Sunday to All Saints' Day, July/August, each day, 1330 to 1615.

Northern Maginot Line Forts - Off the Beaten Path

For those amateur "bunker archaeologists" who like to set out to explore on their own, this page will guide you to the rest of the Maginot Line fortifications. Some people find this the most rewarding way to study military archaeology. For one, there is no entrance fee. Second, you may take as much time as you like to explore (provided your flashlight doesn't run out of power). And finally, you may go wherever you wish. (How many of you, while on a guided tour, have tried to get a peek down the side corridor, or wonder what was down the dark passage or behind the closed door). But there are of course inherent risks.

Remember that these fortifications are approaching 70 years of age. While they will probably be here for centuries, many of their components have deteriorated. Stairway railings have rusted away, and concrete steps are crumbling. Many of the casemates sustained damage during the war and are unsafe. Many others are flooded, a particular danger when the light is poor.

I do not know the status of each fortification. I know that some of them still belong to the army. Others are on private property. Still others are abandoned altogether. (Many were bought up in the early 1970s and later to be used for the salvage of scrap metal). So there is a possibility that, if you don't know whose property you are on, you could be arrested. The best practice, if you don't want to take the chance, is to inquire at the town hall of the nearest village or town. They should be able to tell you who the owner is.

Therefore, be cautious, and never explore alone.

Here is the Maginot Line in the north, from West to East (Some of this information comes from the book "La Ligne Maginot" by Mary and is dated, so information may have changed). I would also like to thank Patrice Lang and Martin Rupp for their contributions.

Fortified Sector of Maubeuge

Petit Ouvrage Les Sarts - 2 blocs - Located in the old Fort des Sarts, built in 1878. North of Maubeuge on N2, just north of la Grisoelle. In very poor condition. All metal removed by salvagers.

Petit Ouvrege de Bersillies - 2 blocs - Located east of N2, on D228, just north of the town of Bersillies. Sits atop the superstructure of a small postion of the same name built in 1891-1893. Now in ruins, all metal removed.

Petit Ouvrage de La Salmagne - 2 blocs - Exact location unknown. Probably on D28 between Elesmes and Vieux Reng. Modernized version of a fort built before 1914. Same condition as the two above.

Petit Ouvrage du Boussois - 3 blocs - Located northeast of the town of Boussois (just off N49, about 5km east of Maubeuge - road not marked). Built on top of Fort Boussois (1880). All metal removed, staircases have been blocked.

Fortified Sector of Montmedy

Gros Ouvrage du Chesnois - 6 blocs - Located north of N43 between Montlibert and Thonne-le-Thil (about 7km north of Montmedy). The entrance block (Bloc 7) has been walled up with cinder block and the combat blocs are covered with thick brush. The 75mm turret of bloc 5 has been removed.

Petit Ouvrage de Thonnelle - 4 blocs - Located on a small road off of N43 just south of Thonnelle (turn left), which connects with Le Fresnois. Bloc 4 contains the only remaining turret weapon in this sector. The rest is covered with brush.

Gros Ouvrage de Velosnes - 5 blocs - Located due south of the village of Velosnes, probably on the first right off of D118. Entrance bloc has been bricked up.

Fortified Sector of La Crusnes

Petit Ouvrage du Chappy - 2 blocs - Located about 1 km east of Longuyon, first right off of D17a towards "Chappy." Today it is abandoned, but has not been scrapped.

Gros Ouvrage de Latiremont - 8 blocs - Located in the Bois de Latiremont. Easiest access would appear to be off D18a just out of Beuville (south of Fermont) towards Doncourt-les-Longuyon. Turn on road which runs north and west of Doncourt Cites, along the woods, then road turns back east - look for casemates to the left. Currently abandoned.

Petit Ouvrage du Mauvais Bois - 3 blocs - Located off of D125a between Laix and Villers-la-Montagne, in the Mauvais Bois. Privately owned; metal salvaged. Condition unknown.

Gros Ouvrage du Brehain - 10 blocs - Located in the Bois du Luxembourg. Entrances are located southwest of N52, about 1km from village of Crusnes. Combat blocs are located north of N52 between Brehain la Cour and N521 exit off of N52. Current status unclear.

Petit Ouvrage d'Aumetz - 3 blocs - Located about 1/2 km southeast of town of Aumetz. Appears that only small forest roads lead to the fort. Mostly scrapped, metal removed, covered up. Doesn't sound like there is much to see.

Fortified Sector of Thionville

Gros Ouvrage de Rochonvillers - 11 blocs - Located on an army camp north of the town of Angevillers. Currently in use by the army.

Gros Ouvrage de Molvange - 9 blocs - Located on military terrain on a hillside west of the village of Entrange. Owned and used by the army.

Gros Ouvrage de Soetrich - 8 blocs - Located north and south of D57 just off of N53 about 1km north of the village of Soetrich. Abandoned - lost in the woods. Update as of July 1997 - Soetrich has been covered over by the army to prevent accidents. (But it is still accessible)

Gros Ouvrage du Kobenbusch - 9 blocs - Located in the Cattenom Forest. Take D56 towards Cattenom. Just before the nuclear plant on the right and the lake on the left, turn down the forest road. The ouvrage is about 1km down on the left. Owned by EDF The fort is flooded and has blocked just inside the main gallery.

Petit Ouvrage d'Oberheid - Single bloc monolith - Continue along the forest road, take first left, then first right. Oberheide is at the end of the forest road. Privately owned. Oberheid has been covered over by the army and is no longer accessible.

Gros Ouvrage du Metrich - 12 blocs - Southeast of Koenigsmaker. Take D2 south toward Buding. Metrich is on the ridge to the left. See the U.S. Army's "The Lorraine Campaign" in their World War II series for a good description of the American fighting on this ridge towards Hackenberg. Metrich is privately owned.

Gros Ouvrage du Billig - 8 blocs - Continue down D 2, turn left onto D255b. Turn left into the forest road just past the village of Briestroff la Petite. This will take you to the entrance bloc. When I was there it was locked up. The week before it wasn't. If you continue on D255b you will see some of the combat blocs in the woods at the crest of the hill.

Fortified Sector of Boulay

Petit Ouvrage of Coucou - 2 blocs (plus the shelter of Coucou, which is located in the same area). Located where D60a (which comes from Monneren) curves into Kemplich. There is a hill right by the curve. The ouvrage and shelter are on the hill. Coucou is privately owned.

Gros Ouvrage du Mont des Welches - 7 blocs - Located half way between Kemplich and Dahlstein, along D118n. You can't miss the hill sticking up on the east side of the road. A forest road, which becomes narrower and more overgrown, takes you right to the munitions entrance. This ouvrage was spectacular to visit. It was wide open when I last visited. Follow the main gallery from the munitions entrance and take the first branch to the left to bloc 4. It is very unique and you can climb outside to take a look at it. It is two story, with 1 75mm turret on the top floor, and two 81mm mortar embrasures in the lower floor. The rest of the fort is very interesting. There is a very unique staircase leading to bloc 5. This is great candidate for restoration!

Petit Ouvrage du Hobling - 4 blocs - Turn right off D918, just before Chemery-les-Deux onto D118j towards Hobling. Go straight past the village, which will be to your left. The road leads into the woods. At the clearing, you will see some cupolas to your right. In the clearing across from the cupolas you will see what is left of Hobling. This is an example of a fort which was destroyed by the metal salvagers. The cupolas are chopped off and the machine gun turret of bloc 3 has been removed, leaving a gaping hole in the field. You can gain entrance in bloc 2, if you can get across the ditch, and through the escape door of bloc 1. Continue down the road and about 2km further down, just beyond the railroad overpass, is an interval shelter. You can explore the shelter.

Petit Ouvrage de Bousse - 4 blocs - Take first left after entering the village of Hestroff. Take the road to the left at the fork. About 1/2km down the road is a military road leading to the entrance bloc. When I found this bloc, it looked like it was being used by a farmer to store hay.

Gros Ouvrage d'Anzeling - 9 blocs - A very unique structure, located south of D3 between Hestroff and Anzeling. The entrance blocs are located off of D53 southeast of Bockange. In the center of the ridge is bloc 9, which is situated far to the rear of the main combat blocs, which are in the woods further north, along the ridge. I have no knowledge of its current status.

Petit Ouvrage de Behrenbach - 3 blocs, not connected. This is actually 3 separate blocs. The stairwells were cut, but the steps only go down about 2 flights, then they end. The stairwell is covered over with wood and was never finished. It is in very bad condition.

Petit Ouvrage de Bovenberg - 6 blocs (bloc 3 not connected). Located east of D154E, parallel to the village of Eblange. Take the first left along the woods and you can see some of the casemates on the ridge to the left. One of them has a chalet built on top of it.

Petit Ouvrage du Denting - 3 blocs - Exact location unknown, but I suspect it is off of the road between D954 and the village of Denting on the left, going toward Denting. Mary does not have much to say about it.

Coume - There are four ouvrages located around the village of Coume which is on D72; Village de Coume (3 blocs - on the left before entering Coume); Annexe Nord (Single bloc, south of Coume); Coume (Single bloc - south of Annexe Nord); Annexe Sud (4 blocs - also south of Coume). The last are located on the road which leads from Coume (first right past the village, before the cemetery) to Bisten-en-Lorraine. All are open.

Petit Ouvrage de Mottemberg - 3 blocs - Located behind a barbed wire fence on what appears to be a farm, along D25 just outside and northwest of Boucheporn. Mottemberg belongs to a scrap metal dealer who has destroyed it completely. Even the steel railings in the stairwells have been removed. Blocks 2 and 3 are in ruins.

Fortified Sector of Faulquemont

Petit Ouvrage du Kerfent - 4 blocs - Located at the end of the forest road in the center of the town of Zimming, which is between Autoroute A4 and N3, in the Bois de Kerfent (east of the village). There are some photographs of Kerfent taken in June 1940 after the German occupation, in the book "On A Livré La Ligne Maginot" by Roger Bruge. I ventured into Kerfent. The entrance is at the end of the forest road. This ouvrage is flooded. The depth at the foot of the staircase is to the top of the shoes - it gets deeper as you work your way to the principal gallery, and is very dangerous. You can get a good idea of the damage done by the German 88mm anti-aircraft guns on bloc 2 of this fort.

Petit Ouvrage D'Einseling - Single bloc - Located on the Einselingerberg to the east of the town of Bambiderstroff. Heading south on D74 through Bambiderstroff, take a left at the exit to the village, just past the church and cemetery (which is on the left), before D74 curves 90 degrees to the right. You may have to park along this road about half way down (1 km) and walk to the north throug the fields to the ridge. Further down the road you will cross over D910 where the road turns into D110d towards Teting. Just past the intersection are some interesting casemates off to the left - the Casemates des Quatre Vents. Just beyond the casemates and under the electrical pylons, take the first road to the left towards...

Petit Ouvrage du Laudrefang - 5 blocs - This should be found at the end of the road. Laudrefang is now abandoned.

Petit Ouvrage du Teting - 3 blocs (bloc 1 not connected) - Located just past Teting Camp and before D20, off to the left. Also abandoned and open and disappearing into the vegetation. Only access is through the emergency exit in block 3. Teting is the last ouvrage before the Sarre gap, also called the Zone of Inondation. The next ouvrage is Haut Poirier, about 30 km away.

Defensive Sector of the Sarre

Petit Ouvrage d'Haut Poirier - 4 blocs - Void of artillery coverage by its neighbors. Located on the Rohrbach Plateau, on a hill overlooking the village of Achen. Drive on D84 to the town square of Achen with a small traffic circuit. turn right and follow the road north up the hill until you reach a church. Behind the church turn left and follow the road out of town. Turn left, then right and stay on this road. Drive straight through the next intersection. This will bring you directly in front of Haut Poirier after less than a mile. Haut Poirier is an excellent fort to visit because there is very little vegetation blocking its view (thanks to the sheep - but watch your step!). Unfortunately, the ditches have been filled up and every entrance has been blocked.

Fortified Sector of Rohrbach

Petit Ouvrage de Welschoff - 3 blocs - Take D84 from Rorhbach-les-Bitches in the direction of Singling. After entering Singling, look for a small intersection with a few roadsigns which can be easily missed. Follow this road until you reach Welschoff Ferme. Behind the farm are two houses. Between the entrance to these buildings is a small path leading away from the road between two hills. The entrance block is straight ahead in the woods. When I drove by Welschoff, there were many cars parked there and it looked as though it belonged to a club of some sort. (I have found out that this was actually the casemeates of Singling North and West which are owned by a shooting club. There are many casemates in this area, since these forts were something of an afterthought. Welschoff also has some interesting camouflage which resembles trees and some false gun turrets made of concrete. Welschoff is very interesting to visit because much of the damage caused by the Germans was repaired. Block 1 is a must see.

Gros Ouvrage du Schiesseck - 11 blocs - Located on either side of D35, between Simserhof and Bitche. The munitions entrance can be found on the first right past the Freudenberg Farm, which is at the junction of D35 and D35a. The men's entrance is across the road in the woods. The combat blocs are on army property, as are most of the fortifications around Bitche.

Petit Ouvrage d'Otterbiel - 5 blocs - Located east of D962, north of Bitche, on a prominent hill. On army property, used for munitions storage.

Gros Ouvrage de Grand Hohekirkel - 7 blocs - Located along the D35, just beyond the Camp de Bitche, on army property. I wouldn't even try to approach these.

Fortified Sector of the Vosges

Petit Ouvrage de Lembach - 6 blocs - Located southwest of the town of Lembach, across the Sauer River, on the road to Mattstal. Abandoned.

Fortified Sector of Haguenau

Gros Ouvrage du Hochwald - This is the largest fortification in the Maginot Line, with 14 blocs, 3 entrances, 9 counterscarp casemates protecting the anti-tank ditch (only Hackenberg has a tank ditch), and 8 km of underground galleries. It is the only ouvrage with two separate underground caserne areas, one on each side of the mountain. Unfortunately, it is still used by the French Air Force. However, Hohnadel/Truttman, in their guidebook, state that some visits may be possible
