saw this browsing the homepage a little while ago, read the story and im absolutely dying for an answer or even a little insight
i've read well over 200 comments from the imgur post and the original French discussion board (mostly the same 4-5 references), and nobody has the foggiest clue what it was built for. one of the comments suggested this would intrigue /x/, so i bring it to you with burning curioisty
still reading the original OP's thread on the french board, no further pics yet but he says
"I mean the security perimeter / ban I saw it was a fence that surrounded the main building and the parking for employees, there where I took the photos and where j ' I found the hatch is in the countryside with cows in a place which is not a military installation"
(very roughly translated via google)
well i read (skimmed) all 61 fucking pages of drivel and the OP only commented about 5 times, revealing almost nothing and saying he wont tell the location because he fears people will hurt themselves trying to go in there
My guess is that it's an old nuclear silo / bunker converted for use for another purpose.
The LED panel gives it away, I think.
Probably just the maintenance area of a larger complex
ce FDP a pas voulu nous le dire mais ont l'a stalk il semblerais que c'est en Bretagne près de Rennes en Ille-et-Vilaine ont en sais pas plus mais d'après les photo il y a un chateau d'eau à l'ancienne(conique vers le bas) ont cherche toujours via Maps mais un département comme la Bretagne c'est grand
Faut qu'il retourne dans l'trou et qu'il chouff ce qui est noté sur l'extincteur ( date de maintenance, etc ) pour avoir un indice sur de quand qu'ca date.
Par contre faut pas trop révéler nos instal nuk ici, ça risque de compromettre notre darkplan d'invasion de zitazuni. (argot codé pour pas qu'ils decryptent, tkt)
The https://en.wikipedia.org/wiki/Biological_hazard symbol on that shit wtf ?
It's written :" équipement scientifiques & industriels S.N". or in english "scientific and industrial equipment S.N."
Not sure about the S.N. part
It looks like a filtration system. Anyway it seems like a standard equipment if they are pumping underground water. Air filter or water. Pic is too blurry.
But what seems odd is the guy was descending the stairs for 45mn it may be fake for more creepiness.
Clearly not it, you fucking flog.
The biohazard symbol was for the ventilation system, warning that the filters could contain hazardous organisms, and that a mask should be used when changing them.
