Simon Marks, 37, came across something quite weird. He has been living in the same house for a long time, but it wasn’t until lately that he realized he was unaware of what was concealed in the home he purchased many years ago.

He came across what he thought was a flowerbed one day while trying to park his car. His car’s wheels were stuck, and he heard unusual cracking noises emanating from the driveway.

“Well, this day couldn’t get any worse,” he reasoned.

When Marks knelt down to investigate more, he discovered that the driveway pavers had cracked, and the driver began to give way. The sound of breaking pavers led to an incredible discovery.

He discovered a piece of metal beneath the soil after removing all of it. Marks clutched the metal piece and tried to pull it out, unaware of what may be lurking beneath the driveway. He then walked around to find out more about the odd thing.

Not knowing what to do next, he contacted his father for assistance, and the two of them were able to carry away a large amount of thickly packed muck, which finally led to an opening. There was an old, rusted ladder there, and the two guys climbed down to see where it would take them.

“My father saw it and immediately said it was an air raid shelter,” Marks explained. “We looked it up on the internet and discovered there are quite a few in this area.”

The bunker they uncovered in Marks’ yard appears to have been erected during WWII.

“The previous owner had to have known it was there, and when he built the house and put in a garden, he had to fill it in,” Marks added.

During the war, these shelters were built to protect civilians from bombardment. Sir John Anderson is believed to have invented them.

“One of the walls is bricked up.” I’m 90% certain we won’t find out about any additional rooms, but we don’t know. “When the house was built, they might have bricked up one of the walls to make way for the foundations,” Marks speculated. “If that’s the case, we’ll just have to leave it,” he continued.

His tale went viral after he uploaded images of his discovery.

Marks and his father intend to restore the shelter because they feel it is a significant historical landmark. According to them, even if that period of history is long gone, it should not be forgotten since it gives us a taste of what life was like back then.
