A routine renovation of a football pitch in Vienna has led to a remarkable archaeological discovery — a mass grave containing the remains of at least 129 individuals, believed to be Roman soldiers. Unearthed in the Simmering district last autumn, the site could mark one of the most significant finds related to Roman warfare in Central Europe.

The unexpected discovery was made at Ostbahn-XI-Platz, where construction workers stumbled upon human skeletons. Excavation quickly followed, led by archaeologist Michaela Binder. “In the context of Roman military history, this is truly one of a kind,” she said. “We’ve found battlefields with weapons in Germany, but finding the actual dead soldiers is unprecedented.”

The grave, which measures around 5 by 4.5 metres and up to half a metre deep, revealed bodies stacked atop one another in a chaotic manner — suggesting they were buried hastily, likely following a violent conflict. The disordered state of the skeletons, many with entangled limbs, further supports the idea of a rushed, mass burial rather than any kind of formal interment.

Anthropologists examining the remains confirmed all were male, mostly aged between 20 and 30, and in generally good health. Many were unusually tall for the time — over 1.7 metres — and showed no signs of malnourishment or disease. However, every skeleton studied bore evidence of violent injuries inflicted at or just before death. Sword slashes, spear wounds, and blunt force trauma, particularly to the skulls and pelvises, ruled out execution and pointed clearly to battle injuries. “These were not executions,” said Kristina Adler-Wölfl of the Vienna city archaeology department. “This was a battlefield.”

Carbon dating places the burial between 80 and 130 CE. Roman military gear found at the site — including a silver-inlaid dagger, fragments of scale armour, a helmet cheek piece, and hobnails from soldiers’ boots — helped narrow down the timeframe. A spearhead found lodged in a hip bone reinforced the conclusion that these men died in combat.

Historians believe the grave is most likely connected to Emperor Domitian’s campaigns along the Danube, which took place between 86 and 96 CE. During this period, Roman forces clashed with Germanic tribes on the empire’s northern frontier, suffering severe losses. Written records suggest entire legions may have been wiped out. This mass grave could be the first solid archaeological evidence of those bloody encounters.

Unlike the highly ritualised burials typical for Roman soldiers, the remains here were unceremoniously dumped into a single pit — no cremation, no markers, and no attempt at orderly arrangement. It paints a picture of a panicked aftermath, possibly following a devastating defeat.

Beyond its military significance, the discovery also offers new insights into Vienna’s early history. The Roman settlement of Vindobona — located just seven kilometres away — would eventually become a key garrison town and the precursor to modern Vienna. Some researchers suggest that tragic events like the battle behind this grave may have contributed to the expansion and strategic importance of Vindobona in the Roman Empire.

Excavations are ongoing, and further analysis, including DNA and isotope testing, is planned. These studies will help uncover more about the soldiers' origins, possibly shedding light on their ethnic backgrounds and whether they were locals, Roman citizens, or recruits from distant parts of the empire.
