This giant sinkhole is so vast that it threatens to swallow the bungalow that sits just beside it.

The cavernous hole has emerged in the back garden of the home in Scorrier, Cornwall, and it drops approximately 90m deep to water.

However, experts believe it could be as much as FIVE TIMES deeper and may eventually open up to destroy the nearby property that is fortunately unoccupied.

Since drilling was begun to explore the depths of the mine, half a garage and a patio has already disappeared into the hole.

Cornwall is full of abandoned mines and this one was discovered when local experts set out to look for more holes after looking at age old maps.

Stuart Dann, from Mining Eye, said that the discovery was unexpected.

He said: ”There was nothing there at all that shows there was a shaft. The shaft opened up when experts were drilling down the patio.

“Both houses nearby are empty, which is a very good job. It is easy to see the woods fields and houses and assume nothing was there.

"If you go back to 1750, the area was completely different.

"There were dozens of engine houses and hundreds of shafts in the area, which probably looked a bit like a desert.”
