But the so-called "Spanish Stonehenge" is just a small piece of an ancient Spanish landscape flooded by the construction of dams in the 1960s. The Guadalperal Dolomites

Today, the open rocky bottom of the reservoir is cut by about 1

50 granite stones in concentric oval rings around a chamber about 5 m wide, intended for entry through a megalithic passage facing east. He earned the nickname "Spanish Stonehenge", but that is something wrong. Unlike Stonehenge, Guadalperal is not built as an outdoor monument.

The stones that are seen today are the frame of a mound. Once the spaces between the concentric rings would be filled with soil and pebbles, the vertical stones would support the roof of horizontal slabs. A mound of earth would cover all the work; you can still see the remains of this structure in the shore of sand and gravel that now surrounds the standing stones.

At the inner end of the passage marking the entrance of the main chamber, a standing stone or manhir carries a carved image of a snake and several cups. Alkala University archaeologists Primitive Bueno Ramirez describes the stone as "engraved, showing a human body, with shoulders tied and a severed head. On one side of the body [there is] a sine line with a triangular head that could be described as a snake. "Many similar images have been found engraved or painted at the entrances of other dolmens in Spain and the direction of the aisle means that the morning sunlight would help illuminate the image.

Archaeologists have documented more than 400 similar monuments in Spain, most notably along the Tagus and Duro river routes, usually associated with the remains of the earliest agricultural settlements in Spain, and burial grounds in the dolmens often include artifacts from the culture of Bell Beaker. dating to about 4750 years and spreading to Central and Western Europe and Northwest Africa about 4500 years ago.

Extinct body

No human remains were recovered in Guadalperal when archaeologist Hugo Obermeier excavated the site in the 1920s. century, he found polished tools, flint and ceramics — the typical set of megalithic object artifacts, many of which were characteristic of Bell Beaker culture — but no people.

"But we have evidence of excavations in nearby megaliths very close to Guadalperal, such as Azutan, in Toledo, with almost identical architecture where human remains were discovered," Ramirez told Ars. Radiocarbon archaeologists date the remains of people buried in the Azuman dolmens, and since Azutan's construction is almost identical to Guadalperal, Ramirez suggests that they are of a similar age: somewhere between 5000 and 6000 years old.

But the stones themselves may have been quarried much earlier. The ancients often moved the Mennirs from the older tombs, often with the graves themselves, with the inhabitants buried in the new dolmens. "There is evidence that older menhirs were used as the original components of many dolmens," Ramirez and her colleagues wrote in a 2015 book, The Megalithic Architecture of Europe .

  The dolmens were partially exposed to low water in 2012.

Near Roman settlement, the town of Augostóbriga, also lies immersed in the tank. The locals probably still used the monument while the Romans occupied the area. "Other Iberian and European megalithic funerary monuments show usages or rituals of dolmens in Roman times," Ramirez told Ars, though she added that there was no direct evidence of rituals in Guadalperal during Roman times. Aubermeier excavations in the 1920s reveal a Roman coin and the remains of a small hut on the mound around Guadalperal.

The Dolmen and the Roman city are just fragments of the ancient landscape of Spain, drowned under tanks built by order of dictator Francisco Franco in the 1960s. In Guadalperal, the Valdekanyas Dam blocks the Tagas River to create the Valdekanyas Dam. "In this Tagus reservoir we have Roman cities and bridges, Iberian boars, medieval water mills, and plenty of megalithic sites," Ramirez explained. "These underwater sites offer a unique image of the landscape in the 1960s, when agriculture in Spain was not yet mechanized and the ancient sites were completely preserved."

As a result of the construction of the dam, the same has happened all over the country, without regard to the preservation or even documentation of the archeological sites that are being flooded. "This interest in the Guadalperal valleys allows us to bring to the table a problem little known even in Spain: the need to create an inventory of underwater sites and comprehensive documentation of those sites and their heritage values ​​with compensation for areas where this is It happened, "Ramirez told Ars.

This year, drought conditions may make this kind of exploration in some places easier, but it also means that sites like the Guadalperal valleys are exposed to tourists whose foot traffic and the study can And Guadalperal is just one good rainstorm away from disappearing underwater again for a few more years – and it could be in worse shape.

The flood was not of the porous granite of the mechirah, much of it which show signs of erosion and some of them are starting to crack. Some stones that stood in the 1920s have since fallen. Due to these concerns, a heritage organization in Spain called Raices de Paraleda is advocated moving the monument to a higher place o

But relocation efforts would be costly and risk erasing important information about the context of artifacts and structures, which may tell archaeologists how ancient people built and used the site. "Before making any decision, it is essential that you have information about the archaeological context and the area around the monument," Ramirez told Ars. "It is also important to consider all the legal issues affecting this case."

Even if the mere movement of the dolmen is possible, it still leaves other places, such as the Roman city of Augustostobrig, all washed away.
