As humans, it’s just our natural tendency to look at the unknown and assume the worst. We can only blame sci-fi books and movies for this. When this jogger spotted these rather sinister-looking structures around the local park in the UK, he just had to ask the big question – What are these?
We mean, can you blame him? They literally look like the entrance to a bunker or some sort of secret research facility. As it turns out, the truth was fairly boring. They’re just vents for underground gasses. Sadly, sometimes, life is nothing like the movies. Bah, humbug!
