Of all the things you could discover in the woods, one of Hitler's bunkers is in the top three creepiest options. This is exactly what happened to a photographer / urban explorer named Marc Askat during an expedition through some woods in northern France.
Askat stumbled upon this bunker while looking for things to photograph. He certainly found some interesting subject matter. It is believed that this building was one of the last bunkers Hitler used during the War. It was likely where Hitler planned the invasion of Britain.
The bunker, which sits at an as-yet still undisclosed location, is as creepy on the inside as it is on the outside. Askat published many photos of his spooky trek through the bunker, that are both of historical interest and fodder for making your skin crawl.
