Britain's THIRD monolith mysteriously appears in Dartmoor after others were found in Glastonbury and the Isle of Wight

The third mysterious metal monolith in the UK measuring 2.5 metres tall has now appeared on Dartmoor.

The 'surreal' sculpture was spotted on the top of a hill in the Devon National Park near the village of Throwleigh.

It appears to be the third of its kind found in the UK since Tuesday, with one in the Isle of Wight and another in Glastonbury.

The installations were first spotted in Utah in November and have since been popped up around the world.

The structure was spotted on Dartmoor by photographer Sarah Clarke, who captured an eerie shot of the monolith on Wednesday

Two similar monoliths have appeared on the Isle of Wight and on top of a hill in Glastonbury

One also appeared in the centre Ukranian capital of Kiev on Zamkova Hora hill on Friday, and another appeared in Poland. 

Australia has also been embroiled in the global trend, as one of the metal structures appeared in Adelaide. 

The structure was spotted on Dartmoor by photographer Sarah Clarke, who captured an eerie shot of the monolith on Wednesday.

She shared her image on Twitter and had to reassure her followers that the image wasn't photoshopped.

She said: 'So, a very exciting morning - it's a real thing!

Another was discovered in a field in Assened, in Belgium, similar to the others around the world

The monolith in Adelaide Australia also was set up in the middle of a field

This metal sculpture was discovered in the nature reserve area Tiendeberg, in Riemst, also in Belgium

'Anyone who knows me, knows I just can't do Photoshop so, take it from me.'

Mark Bullock, who went to look at the pillar on Wednesday, said its vantage point on the hill made it appear like 'something was wrong with the sky'.

He added: 'It was a bit surreal.'

Dartmoor National Park have since removed the monolith, saying that the moorland is protected.

A spokesperson said: 'We know people may think these types of things are an interesting talking point, but it must be remembered that Dartmoor is a protected landscape for its importance for wildlife, nature and archaeology.'

The mysterious monoliths first started popping up around the world following the removal of a mystery piller in Utah. 

It was removed by rangers who said people had been congregating near the structure and creating a lot of litter and mess.

The mysterious triangular metal monolith that appeared in the remote Utah desert on November 18 and captured the attention of the nation vanished on Friday

The appearance of the monoliths has sparked comparisons to the Stanley Kubrick film 2001: A Space Odyssey.

Others have popped up across the US, in Colombia, Romania, Holland, the Isle of Wight and most recently Glastonbury.

The Most Famous Artist, also known as Matty Mo, is thought to have been behind some of the other monoliths that appeared in the US. 

Designer Tom Dunford also admitted he had installed the monolith in the Isle of Wight in tribute to others that had popped-up.     

But it remains a mystery as to who is behind the monolith on Dartmoor. 

The monoliths in Romania and a Utah desert were also removed after their brief stints of notoriety. 

On Tuesday, images emerged of four men working in the dead of night to remove the strange, triangular pillar from the desert in Utah.

It was spotted a few metres away from the well-known archaeological landmark the Petrodava Dacian Fortress, which is the oldest historical monument in Piatra Neamt.

The shiny pillar, which protruded some 12 feet from the red rocks of southern Utah, was first spotted on November 18 by baffled local officials counting bighorn sheep from the air.

News of the Utah pillar's initial discovery quickly went viral around the world, with many noting the object's similarity with strange alien monoliths that trigger huge leaps in human progress in Stanley Kubrick's classic sci-fi film '2001: A Space Odyssey.' 

Some observers pointed out the object's resemblance to the avant-garde work of John McCracken, a US artist who lived for a time in nearby New Mexico and died in 2011.

But McCracken's representatives have given ambiguous and at times conflicting responses to this theory, prolonging an international guessing game that intensified further with the monolith's sudden removal Friday.

Another monolith appeared on the street outside Grandpa Joe's candy shop in Pittsburgh on December 4, but it was later revealed the store's owner has commissioned it to capitalise on interest in the structures

The Romanian monolithn was also removed a day after it was erected.  

A spokeswoman for Piatra Neamt police, Georgiana Mosu, said officers are conducting an inquiry into the illegally-installed structure, which was positioned in a protected archaeological area from November 27. 

Another monolith appeared outside a sweet shop in Pittsburgh last Friday.

However, owner of the Pittsburgh candy store, Christopher Beers, has revealed he commissioned the 10-foot tall, 24-in wide triangle of plywood covered in sheet metal to capitalise on the recent interest in the mystery structures.
