V1: the flying bomb
A V1 flying bomb
The Siracourt bunker
This bunker was built 5 km away from Saint-Pol-sur-Ternoise, right in the heart of a farming village (which, totally destroyed by the Allied bombings, has been rebuilt in a very original manner). The bunker was designed to store and launch the V1 flying bombs. The 212 metre long building is clearly visible, but all access routes to its interior have been sealed up.
The Lottinghem bunker
The construction of this bunker was swiftly abandoned after very heavy Allied bombings.
