There are two forts on Mont Barbonnet. Suchet Fort was built at the top between 1883 and 1886 in the same context as the Authion one. A Maginot-style fort was built into the mountainside further down between 1931 and 1935 to strengthen the site’s defensive system.
It’s very discreet so it’s a surprise to see how big it is once you get there. It feels like a castle as you take moat-like paths to get there.
Nature has taken over here. The total silence reigning over the site makes you feel like you’re in another world. Graffiti in the barracks proves that there were actually soldiers here and they give the fort a touch of magic.
