This is an eeire Cold War bunker that has been left untouched for the last 40 years.
Explorer Becca Morgan, 23, visited the bunker with her partner, and the two were shocked to find everything inside exactly as it was when it was in use during the Cold War.
The explorer, from Bath, Somerset, UK, said: "When we entered, I was so surprised to see everything left exactly as it was back when it was last in use in 1981. All the items were left behind exactly how they should be, and there were even some old drinks that have been discontinued."
The bunker, in Bristol, UK, was built in 1953 to protect people against the threat of the nuclear bomb. According to Becca, the bunker was redeveloped in the 1960s and was actively used until 1981, when it was abandoned.
She said: "I love documenting abandoned places on my social media for people to see who may not be as adventurous as me. Not everyone sees an abandoned building and thinks, 'Let's enter.'
"I think people can be intimidated by them, as you never know what's lurking around the corner inside. They aren't necessarily safe places to be entering!"
Earlier we reported how on another abandoned bunker from the Cold War. An abandoned Soviet nuclear bunker that was built to survive World War 3 but was then abandoned has become popular among urban explorers and could soon be open to the public as well.
Zeljava Underground Airbase, located in the Balkans on the border between Croatia and Bosnia and Herzegovina, was once among the largest military complexes in Europe. It was built to withstand a 20-kilotonne nuclear blast during the Cold War.
Following the break-up of Yugoslavia in the 1990s, the facility was destroyed using powerful explosives and was eventually abandoned in the Serbo-Croatian war in 1992. The remains of its huge doors are still visible, but the facility sat in disrepair after its destruction, attracting adventurous tourists who wanted to explore the ruins.
Mirsad Fazlic, a former pilot who worked at the base for nearly a decade in the 1980s, said: "All the systems were state-of-the-art at that time. It was the then best military and civilian technology."
The airbase featured in a 2016 film called 'Houston, We Have a Problem!' and since then, locals believe more than 150,000 people a year have visited it. Authorities in the area are reportedly hoping that even more tourists could visit, and there are plans to create tourist trails.
Photographer Angelo Virag, who visited the airbase while staying in the Croatian capital, Zagreb, said the area is "frozen in time" and added he was in awe of the "absolute ingenuity of engineering". His cousin Mario Garbin, from Perth, Australia, said he was amazed at the "raw, authentic nature of the infrastructure that has been left untouched for the last 30 years".
