2,200 years ago, Building G in the archaeological site Tossal de Baltarga burned to the ground. Building G’s charred remains preserve a moment in time for this Iron Age village, telling us about the livestock the villagers kept, the food they cooked, the cloth they made, the treasures they prized — and the loss of all of these things. The destruction of Tossal de Baltarga, which occupied a strategic position in the Pyrenees, may have been linked to Hannibal’s army marching through this region to fight the Romans during the Second Punic War.

A ruined building in the middle of the Pyrenees records a tragedy for the people who lived there — a devastating fire which burned a settlement to the ground, destroying everything down to a hidden gold earring. Now archaeologists’ excavation of Building G, in the strategically placed Iron Age site of Tossal de Baltarga, reveals a way of life derailed by violence: potentially, a forgotten episode of the war between Carthage and Rome.

“The destruction was dated around the end of the third century BCE, the moment where the Pyrenees were involved in the Second Punic War and the passage of Hannibal’s troops,” said Dr Oriol Olesti Vila of the Autonomous University of Barcelona, lead author of the article in Frontiers in Environmental Archaeology. “It is likely that the violent destruction of the site was connected to this war. The general fire points to anthropic destruction, intentional and very effective — not only Building G, but all the buildings of the site, were destroyed. In Building D we found a complete dog, burned…”

Buried treasure

Tossal de Baltarga was a hillfort of the Cerretani community, who had a major settlement at nearby Castellot de Bolvir. It seems to have lacked defensive walls, but commanded an excellent view over the river and critical travel routes. Its sudden destruction preserved organic remains, which allowed archaeologists to paint a detailed picture of the life that its occupants lived until it was set alight.

“These valleys were an important territory economically and strategically,” said Olesti Vila. “We know that Hannibal passed the Pyrenees fighting against the local tribes, likely the Cerretani. Not many archaeological remains of this expedition are preserved. Tossal de Baltarga is likely one of the best examples.”

Building G had two floors. The fire burned so fiercely that the roof, support beams, and wooden upper floor fell in, but some of the valuables survived the fall: the archaeologists found an iron pickaxe and the gold earring, concealed in a little pot.

This upper floor seems to have been divided into spaces for cooking and textile production. Numerous spindle whorls and loom weights were found, which could have been used to spin and weave wool from the sheep and goat that lived on the lower floor. Archaeologists also found edible grains like oats and barley, and some cooking vessels, with residues that showed the people who used Building G had been drinking milk and eating pork stews.

A memory of conflict

While no human remains were found in Building G, six animals did not escape. The four sheep, goat, and horse — which may have been ridden by the owners of Building G; it was old enough and a metal horse bit was found — were penned up in their wooden enclosures with their feed. They could even have been trapped by a closed door, which would explain burned wood found in the entrance. This penning might have been a departure from usual practices, caused by the fear of conflict: isotope analysis indicates some sheep had previously grazed in lowland pastures, possibly by arrangement with other communities.

“These mountain communities were not closed in the highlands, but connected with neighboring areas, exchanging products and, likely, cultural backgrounds,” said Olesti Vila. “The complex economy indicates an Iron Age society adapted to their environment and taking advantage of their resources in the highlands. But it also shows their contact with other communities.”

“Our reconstruction implies a sudden destruction, with no time to open the door of the stall and save the animals,” added Olesti Vila. “This could be just an unexpected local fire. But the presence of a hidden gold earring indicates the anticipation by the local people of some kind of threat, likely the arrival of an enemy. Also, the keeping of such a high number of animals in a little stall suggests the anticipation of a danger.”

Archaeologists don’t know what became of the people who were living at Tossal de Baltarga, but it was eventually reoccupied, and garrisoned by the Romans. Some part of the community likely survived the conflagration. Perhaps remembering the burning of Building G and its neighbors, these later occupants of Tossal de Baltarga constructed defenses — including an impressive watchtower.
