A state-of-the-art solar plant was supposed to bring renewable energy to Spain—but instead, it uncovered a 5,000-year-old mystery. When construction crews broke ground in Almendralejo, they stumbled upon ancient settlements, leading to the discovery of a massive hilltop fortress with fierce defensive systems and even a skeleton with a dagger ominously placed on its back. What secrets does this lost civilization hold? Let’s dig in.
A Solar Project Unearths a 5,000-Year-Old Mystery
What started as a push for clean energy in Spain turned into one of the country’s biggest archaeological finds. During construction in Almendralejo, workers stumbled upon the remains of Cortijo Lobato—a massive Copper Age fortress. But that wasn’t all. Among the ruins lay a chilling discovery: a Roman soldier’s skeleton, buried face down with a dagger ominously placed on his back.
Spain’s Largest Copper Age Fortress
Built nearly 4,900 years ago, Cortijo Lobato was no ordinary settlement. Spanning 13,000 square meters (140,000 square feet), it had three concentric walls, 25 towers, and deep defensive ditches. It was designed to withstand prolonged sieges, reflecting an era of intense conflict. This find challenges previous beliefs about the Chalcolithic period—suggesting warfare was far more organized than historians once thought.
A Violent End—The Fall of Cortijo Lobato
For four centuries, the fortress stood strong—until it was suddenly abandoned around 2450 B.C. Evidence points to a catastrophic assault. Carbon dating of burnt remains suggests an intentional attack, with flames engulfing the settlement. The narrow 27-inch-wide entrance was meant to trap invaders, but ultimately, the fort’s defenses failed. The abundance of arrowheads found at the site tells the story of its final, brutal battle.
A Mysterious Roman Burial
Nearly 2,500 years after the fortress fell, another event unfolded on this site. A Roman soldier, aged 25-35, was buried face down, his feet severed, and a sheathed dagger—called a pugio—placed on his back. This wasn’t a traditional burial. The shallow grave suggests a hasty disposal, and the face-down position hints at disgrace. What had this soldier done to warrant such a fate?
A Dishonorable Death?
In Roman times, burial customs were steeped in symbolism. Being laid face down often signified shame or punishment. The severed feet add another layer of mystery—were they removed as a warning, or was it a brutal act of execution? The dagger, a standard-issue weapon of Roman legionaries, was positioned deliberately. Could this man have been a deserter, a traitor, or a victim of battlefield justice?
The Legion That Roamed Spain
At the time of the soldier’s burial (2nd–3rd century A.D.), only one Roman legion operated in Spain—Legio VII Gemina. Unlike other military units, this legion specialized in road security rather than warfare. If the buried man belonged to this legion, his gruesome end becomes even more puzzling. Was he a soldier caught in a local conflict, or did he meet his fate at the hands of his own comrades?
Clues in the Fortress Ruins
Beyond the soldier’s grave, the excavation unearthed thousands of artifacts that paint a picture of daily life in the Copper Age. Arrowheads, stone axes, loom components, grinding stones, and decorative idols suggest a complex society that balanced warfare, craftsmanship, and trade. The presence of textile-making tools hints at an industry that thrived—until its violent demise.
Engineering Marvel of the Copper Age
The fortress’s pentagonal design was rare for its time, showing advanced strategic thinking. Built with massive stone and adobe walls, it featured three defensive ditches up to 1.8 meters (6 feet) deep. Positioned 314 meters (1,030 feet) above sea level, it provided a commanding view of the landscape, allowing defenders to spot invaders from afar. This level of sophistication rivals even some later civilizations.
A War-Torn Past Revealed
Historians long believed the Copper Age was a relatively peaceful time. The discovery of Cortijo Lobato challenges that notion. The fort’s sophisticated defenses, the sheer volume of arrowheads, and the evidence of an organized assault suggest ongoing territorial conflicts. Early civilizations weren’t just surviving—they were waging war. This site proves that large-scale battles may have been far more common than previously assumed.
How the Solar Project Adapted
Despite the historic find, the $87M solar project didn’t come to a complete halt. Instead, Acciona Energía worked with archaeologists to modify its layout, preserving the excavation site while maintaining power generation. The solar plant was reconfigured to protect key areas, creating a rare fusion of ancient history and modern sustainability—where the past and future now coexist.
The Unfinished Story of Cortijo Lobato
Archaeologists are still working to unlock the full story of this lost civilization. DNA analysis of the Roman soldier’s teeth could reveal his origins, while ongoing digs may uncover more about the fortress’s final moments. Was this a thriving trade hub? A seat of power? A site of ritualistic warfare? Each artifact adds a piece to the puzzle.
What This Means for Archaeology
This discovery is more than just a historical curiosity—it shifts our understanding of early human civilization. The complexity of Cortijo Lobato’s design and its violent downfall force historians to reconsider the scale of warfare in prehistoric Europe. Meanwhile, the Roman soldier’s burial raises new questions about military justice and life in ancient Spain. This site will influence archaeological research for years to come.
