A man named Simon Marks, 37, stumbled upon something incredibly strange. Namely, he has been living in the same house for quite some time, but it wasn’t until recently that he discovered he wasn’t aware of what was hidden in the place he bought some years ago.

One day, as he tried to park his car, he stumbled upon what he believed was a flowerbed. The wheels of his car got stuck and he heard strange cracking noises coming from the driveway.

“Well, this day couldn’t get any worse,” he thought to himself.

When he kneeled down to further inspect the issue, Marks noticed that the pavers of the driveway had cracked and the driver started to give in. The sound of the cracking pavers led to an astounding discovery.

Once he removed all the dirt, he noticed a piece of metal underneath. Unaware of what could be hiding under the driveway, Marks gripped the metal piece and tried to pull it out, but to no avail. He then went around in order to learn more of the mysterious object.

Not knowing what to do next, he called his father for help and both of them managed to cart away lots of densely-packed mud which eventually led to an opening. There was an old rusty ladder there, and the two men climbed down eager to learn where it would lead them.

“My dad saw it and instantly said it’s an air raid shelter,” Marks said. “We googled it and found there are quite a few in this area.”

It appeared that the shelter they discovered in Marks’ garden was built during the WW II.

“The previous owner must have known it was there and when he built the house and put a garden in… he must have filled it in,” Marks explained.
