A building in the middle of nowhere
You’ve probably seen enough horror movies to know where this is going. Instead of the OP high-tailing it out of there like any sane human would do, he decided to snap a picture of this clearly haunted building in the middle of nowhere and ask internet strangers to clarify. It was smart of him not to enter it, though.
But he had nothing to fear. Someone pointed out that this was an old refilling station for steam engine tanks. We weren’t alive when these things were in use, and it’s a real shame that nobody uses them anymore since they’re way more environmentally friendly than diesel.
