A man who bought a new house in Middlesbrough found something that was not in the property's details - a Second World War bunker.
Neighbours told new homeowner Chris Scott about the bomb shelter, something which he had dismissed as a story that had been exaggerated over the years.
But when looking through the overgrown grass in his garden, Mr Scott discovered what he originally thought was a drain pipe cover but once he opened it, he saw a ladder leading underground.
Mr Scott said: "It was actually my builder who convinced me to open it up but I didn’t really want to because I thought it was a drain but he said 'let's have a look anyway'."
The bunker was initially full of water, due to the previous owner apparently using it to water his garden.
After pumping water out the water, Mr Scott gained entry inside the bunker, which measures 5m x 2.5m, and is around six foot in height.
The shelter remains damp, but there are many items left over from the end of the Second World War, including a wooden table which was previously submerged.
A second chamber also makes up the bunker which Mr Scott gained access to by smashing down a wooden door.
He said: "As we looked around we noticed light switches and some snorkel devices to help people breathe once the door was shut.
"We then discovered a second room behind a wooden door.
"We found more light switches, distribution boards and we actually found a light bulb with its elements still intact, so there's a possibility that if you give that power it might light up."
In the second chamber, Mr Scott found another door which was blocked by rubble which he believes "could go down the end of the street" or could be a "secondary escape".
The truth behind the bunker remains a bit of an urban mystery for those in the area.
Some experts believe it could have been a public bunker for 50 people along the street.
Historians say access would have been difficult for children and the elderly, while the high-quality build suggests it may have been a Government building.
Mr Scott has his own theory: "The government due to fear of invasion in the 1940s, actually built small team shelters so you'd have a small team of three or four people.
"The reason it [the bunker] is in two rooms is because the explosives would be kept in one room and the people in the other.
"Then they would wait until two or three weeks after the invasion and obviously they would come out using the explosives to attack strategic targets and disrupt the invaders."
For now, Mr Scott is unsure what the future holds for his bunker but one rock band have approached him over the possibility of recording a music video inside it.
