The temple, once used by the secretive religious sect and believed to date back 700 years, was found behind a rabbit hole in the Shropshire countryside.
It is thought the cave was used by the Knights Templar after their sect was literally forced underground by King Philip IV of France when he publicly burnt several of its prominent members at the stake.
The religious group were rumoured to have carried round the Holy Grail, most commonly identified as the cup that Jesus drank from at the Last Supper and that Joseph of Arimathea used to collect Jesus’s blood when he was crucified.
The incredibly religiously significant artefact has never been discovered, but there is a chance it may have been used by the Knights Templar in Shropshire.
The eerie discovery was unearthed after it lay buried beneath the ground for years
The Templar, which was a much-feared military wing during the Crusades, was exceptionally influential and wealthy, leading the king to fear their power.
King Philip was also heavily in their debt, so he set about rounding up its leading members and torturing them into confessions of treason.
They were then ceremonially executed.
Out of fear that they would lose the artefact during the suppression of their beliefs in 1307, it is believed the order smuggled the Holy Grail to Scotland where it remains buried beneath Rosslyn Chapel.
The Holy Grail could well have passed through Shropshire en route to its final resting place.
However, a 2006 book claims that the Grail was instead taken to Northern Spain, and protected by the Knights Templar there.

The Knights Templar was forced underground after being publicly discredited
The Caynton Caves were not touched for years after being closed off in 2012 because vandals kept carving things into the walls.
Druids and Pagans also flocked to the caves years ago as a place for them to conduct their ceremonies discreetly.
Photographer Michael Scott, from Birmingham, 33, captured the eerie pictures of the inside for the first time since it was shut in 2012.

He said: “I traipsed over a field to find it, but if you didn’t know it was there you would just walk right past it. It’s probably less than a metre underground, so it’s more into the field than under it.
“Considering how long it’s been there it’s in amazing condition, it’s like an underground temple.”
