Over the last 50 years, the Valdecañas artificial water reservoir in Spain has shrunk due to droughts and revealed a 6,000-year-old stone monument. It was dubbed the Dolmen of Guadalperal, and scientists compare it to Britain’s famous Stonehenge.

The monument is a circle of 150 standing stones, with some of them almost two meters tall. By tradition, and in the absence of any other hypothesis, it is believed to be used as a ritual space.
One of the largest stones (presumably marking the entrance) is decorated with a human figure on one side, and a wavy pattern resembling a snake, a river or a road on the other side.
Unfortunately, experts don’t have much time to study the monument, as rains are approaching, and the stones will likely be submerged again.
It was first mentioned in the early 20th century. But back then, amid hectic political developments and construction works nearby, the monument was forgotten. Only the top of the stones above the water reminded rare witnesses of the mysterious ancient monument.
