British explorers were left stunned after discovering a hidden underground Nazi bunker abandoned since World War II.
The group made the eerie find during a trip abroad after spotting a tiny patch of concrete buried in scrubland.
Inside, they found original drawings still etched onto the walls by German troops stationed at the spot during the war.

Stuart, from Forgotten and Forbidden Explores, was stunned to find the seemingly forgotten bunker in France.
He ventured inside the reinforced concrete structure to investigate further, as reported by Need To Know.
Stuart said: “We were about to call it a day in France when my colleague noticed a tiny bit of concrete in the scrub.
“What revealed itself inside blew our minds.
“The bunker is in northern France on an old German airfield from 1940.
“A database gave us an idea of where to look but then it was up to us to go and see.
“The item in question could have been demolished so it’s all luck of the draw.
“But it’s all part of the research.”
Stuart said there was no sign of any modern litter inside the bunker, which suggests that it has remained untouched for decades.
He added: “It’s on private land so I’d expect the farmer knows it’s there.”
The drawings are believed to have been done by Luftwaffe pilots and troops stationed at the airfield.
Among them are eagle sketches – the symbol used by the German air force – alongside writing about pilots needing rest.
