Hello, this weekend for the “journée du patrimoine”, I decided to go there. I thought at first it opened at 10 am because one google file said that. After contacting someone from the association, I found out it actually opened at 2 pm, so I went there with my parents. It’s a museum with parts, militaria and models (there’s a panther roadwheel in there and at the bunker, a AMX turret). The 2 bunkers were small bunkers who got unearthed in 2021.
I assume it’s a drawing of one of the bunkers.
