Mysterious 'Wheel of Giants

Mysterious 'Wheel of Giants' IS as old as Stonehenge: Experts confirm Golan Heights circle is 5,000 years old and may have been used for gruesome 'sky burials'
Prehistoric stone monument of Rujm el-Hiri, or Gilgal Refaim went unnoticed for centuries in the disputed region of the Golan Heights
Archaeologists spotted it thanks to aerial photos showing the circles
Now it is believed to be 5,000 years old - a similar age to Stonehenge
However, the mystery about why the monument was built remains.

It may be one of the Middle East's most mysterious structures, but it's easy to miss from the roadside.
The prehistoric stone monument of Rujm el-Hiri, or Gilgal Refaim, went unnoticed for centuries in a bare expanse of field in the disputed region of the Golan Heights.
Now archaeologists have dated it to 5,000 years old - making it roughly the same age as Stonehenge in Wiltshire - but they still don't know who built it, or why.
Theories include an ancient calendar, or a 'sky burial' site in which dead bodies were placed on top of stone mounds to be picked apart by vultures.
Since this discovery, a number of excavations have revealed it's one of the oldest and largest structures in the region.
And now shards of pottery and flint tools have been used to date the site.
Scholars generally agree construction started as early as 3,500 BC but other parts may have been added to the structure during the following two thousand years.
By comparison, Stonehenge is believed to date back around 4,614 years.

Unlike the famous English monument built using around 100 huge stones topped by lintels, the Golan structure is made of piles of thousands of smaller basalt rocks that together weigh over 40,000 tons.
'It's an enigmatic site,' said Uri Berger, an expert on megalithic tombs with the Israel Antiquities Authority.
'We have bits of information, but not the whole picture.
'Scientists come and are amazed by the site and think up their own theories.'
Standing on the ground inside the complex, it looks like a labyrinth of crumbling stone walls overgrown with weeds.
