'Spanish Stonehenge' dating back 7,000 years emerges as water levels recede
A summer of heatwaves and the worst drought in decades for rural Spain, has revealed a prehistoric stone circle in a dam whose waterline has receded.
Its official name is Dolmen of Guadalperal, but it is affectionally called Spanish Stonehenge.
The circle of stones is believed to date back to 5000 BC.
It's in the Valdecanas reservoir, in Caceres, where authorities say the water level has dropped to 28% of capacity, according to reports.
German archaeologist Hugo Obermaier discovered it in 1926, but the area was flooded in 1963 in a rural development project.
Since then it is believed it has only become fully visible four times.
Little is known about who erected them, though some suspect they are tombs due to human remains found near similar structures around the continent.
