Fort Fermont is a 9 Block construction with two entry blocks and seven combat blocks. Armament of the combat blocks as follows:

      Block 1 : two 75mm cannons

The Fort is situated 30m under ground and had a 600 men crew, one power plant with four diesels (225 kW) one subterranean corridor of one km lenght and an electrical narrow-gauge railway. Again, like the Fort Hackenberg, a little city underground. This fort was able to withstand a german attack from behind on the 21. june, 1940. One French soldier of the Fort's crew was killed in action during the three days combat. He died of a direct hit from the German artillery on his turret on the entry block. A sign in front of the entry block tells his story:

"On June, 21., 1944, the crew entry of the Fort Fermont was attacked by a German PAK, aiming at the right turret, where Soldier Piton was killed.
This German cannon was destroyed by bombs and the 81 mortar of the turret of Block 5, coordinated by the observatory of Block 3.
Florian Piton was the only French soldier to die in the course of this battle. He was provisorily buried within the Fort. Visitors will pass his grave."


The Fort can be reached via the N 18, between Longuyon und Longwy, by following the signs.
