A carpet-fitter has claimed to have solved the mystery of Stonehenge after building a machine.
Steven Tasker, 66, thinks he knows how the giant stones were moved thousands of years ago.
The man from Llanrhaeadr, Denbighshire, North Wales, came up with his idea during a visit to Egypt when he started wondering how the pyramids were built, Wales Online reports.
He thinks a machine was used to transport the stones 180 miles from the Preseli Hills to their final resting place on Salisbury Plain - where they became one of the most popular and mysterious sights in the world.
Steven has recreated a machine he thinks could explain how the stones were moved.
It features a circular board balanced on planks that sit on rockers and wooden feet.

Steven said he has now managed to lift a third of a tonne with it and believes it could "move any weight".
He said the machine was able to defy gravity and could have even been referenced in the bible.
He said: "It may look like something out of Last of the Summer Wine, but we've lifted a third of a tonne with it and theoretically it could move any weight."
Steven started thinking about the process in 2004 and began by creating a prototype involving rockers tied to a plank of wood.
He then counterbalanced a 60kg roll of carpet using pivot points and said it works by retaining the load's centre of mass over the feet.
He added: "The science behind the machine I equate to clown shoes. As long as it is over his feet, even if he is leaning over, it won't tip over. It is like a trick of the eye and appears like it is defying gravity."
Despite his initial beliefs, Steven's prototype had started to gather dust in his garage for several years until, when he went on a tour with Dr Campbell Price in 2018.
Dr Price, who is the curator of one of the UK's largest Egyptology collections at Manchester Museum, was impressed with his theory and invited him to give a talk, which Steven said inspired him to explore things further.
He added: "The story about Stonehenge is a story that keeps giving.
"There are tonnes of theories out there. Everyone that gets a theory writes it on paper and that is what they think. But until you build something like I have it is just a theory.
"It is nice to have the support of the experts. I am not an academic but I am chuffed they like what I have done.
"The Stonehenge machine is really just an adaptation of what I think the Egyptians used.
"99 per cent of the people have posted positive comments. A few have been sceptical and would like to see if it could be built using original techniques.
"That is what I would like, someone to pick it up and build a 1-1 size. At the moment it is just a hypothesis, to actually construct a real one using techniques of that time is the main aim.
"I am convinced after all my research and am chuffed to bits with the response and how the machines works.
"It was an out-of-the-box experiment and when I made it I filmed it with all the mistakes. At the end of the video when I greased the machine up for a speed test I couldn't believe how easy it worked."
During his research, he became stuck on one aspect until a chance encounter at a holiday cottage when he flicked through a copy of the Old Testament.
In one passage, a prophet called Ezekiel describes a "vision of God being transported on cherubim", with four wings and "feet shaped like the sole of a calf's foot".
The "four wings" being planks of wood moving either side, while the idea of "calf's feet" helped him further develop his prototype.
Steven believes large stones were moved throughout Britain to act as clocks, calendars and temples, with Stonehenge one of the most significant sites.
He estimates the machine would have been able to travel 1.5 miles (2.4km) a day - meaning stones could be moved from the Preseli mountains in months.
Experts say his theory offered a "different perspective" on how ancient monuments could have moved.
Engineer Shaun Whitehead, who led the Djedi robotic exploration of the Great Pyramid, said nobody knows for sure how they were moved, Steven's idea is "as good as any, and better than most".
Dr Price said the "efficient movement of large numbers of ancient monuments" has never been fully explained.
He added: "Steve's experiments give a different perspective into how ancient people were able to plan paths of least resistance, and to manipulate natural forces."
