Due to the unfortunate decision-making of General Franco who opted to consign the site to obscurity when he commissioned a valley bordering the Tagus river to be flooded.
But before its rediscovery and subsequent demise, it is thought the stones would have centered around a central chamber for sun worship.
It is believed the Celts living in Iberia 4,000 years ago may have built the structure.
‘The stones have been brought from about five kilometers away to form this temple, which we think was used to worship the sun,’ Ángel Castaño, president of the Peraleda Cultural Association, told the Times.
‘In that way, it has similarities to Stonehenge but is obviously smaller.
‘People here had heard about them but had never seen them. We want the authorities to move these stones to the banks of the reservoir and to use them as a tourist attraction, as few people come to this area.’
Stonehenge’s enormous rocks are up to 30 feet in length, dwarfing the six-foot-tall single monoliths uncovered in Spain. There are more stones at the Spanish site, 1144 compared to 93 in Wiltshire.
However, Stonehenge’s monument covers 10,800 square feet (10,000 square meters), a far bigger area than the Spanish site.
