Ouvrage Otterbiel, Military fortification in Bitche, France
Ouvrage Otterbiel is a Maginot Line fortification near Bitche consisting of four combat blocks and one entrance block linked by underground galleries. The facility includes ammunition storage, command posts, and observation stations within its subterranean network.
Construction of this fortification began in 1931 but remained incomplete due to budget constraints. Several planned artillery blocks and a separate personnel entrance were never built.
The fortification represents French military engineering and defensive strategy during the pre-World War II period, incorporating advanced technologies of that time.
This fortification is located within the Bitche military camp and requires special authorization and guided tours to visit. Explore the underground network and observation areas, but check access rules and visiting times in advance.
The fortification was equipped with three separate diesel generator units, each combining an engine with an alternator for power output. This backup system ensured the facility could continue operating if any single generator failed.
