My point is, most people never know what secrets their homes may be hiding. One man, Simon Marks, from Luton, England, certainly never expected that a hole in his front yard would prove to be the entrance to an underground cavity from the Second World War…We’ll be upfront regarding the fact that this story played out a few years ago, but it makes for fascinating reading nonetheless.

Yet after inspecting the ground, Simon realized that it was no flowerbed he’d rolled his vehicle over, but a two-roomed World War II air raid shelter!

“This massive hole appeared. I thought it was a sinkhole or a badly constructed garden,” the 37-year-old Simon told The Sun.

“I was just terrified the whole house was going to vanish. I took some pictures and sent them to my dad.

“When I moved a few of the slabs out of the way I found a ladder. I got my selfie stick and put it down the hole where I saw two rooms.

“My dad saw it and instantly said it’s an air raid shelter.

“We googled it and found there are quite a few in this area. It is made from concrete lintels and is in immaculate condition.”

As per reports, Simon bought the house from an elderly couple who had build the home in the 1970s. He believes they must have know about the shelter’s existence.

“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,” Simon explained.

“He clearly wasn’t very worried about it and it just sat there until the hatch fell through. I think it’s great and I want to clear it out and preserve it if it’s structurally sound.

“It’s incredible to think it has all been made by hand. It’s part of our history so it should be kept.”

Intrigued by the find, Simon and his father set about excavating the shelter with buckets, revealing the two-room shelter in its entirety.
