Roman Mass Grave Under a Vienna Field Reveals Pelvic Wounds

Beneath a soccer field in a Vienna suburb, construction workers uncovered something that turned a routine sports ground renovation into one of Europe’s most significant Roman archaeological finds. Around 150 young men, all of them killed violently nearly 2,000 years ago, had been buried together in a single hurried pit.

A Discovery Nobody Was Looking For

Construction workers renovating the Ostbahn-XI sports ground on Hasenleitengasse in Vienna’s Simmering district encountered the remains in late October 2024. Archaeologists excavated 129 complete or partially complete skeletons from a shallow pit measuring roughly five by 4.5 meters, with additional displaced bones suggesting the original number of dead may have reached around 150.

“The discovery of an early Roman mass grave with around 150 individuals is a find unique in Europe, and may hold a key to the founding history of Vienna,” said Veronica Kaup-Hasler, Vienna’s executive city councillor for culture and science, at the initial presentation of findings. Kristina Adler-Wölfl, head of Vienna City Archaeology, explained why the find is so rare: “In the Roman Empire there were strict burial rituals, and precise rules had to be followed even after death. Since cremation was standard practice across the European parts of the Roman Empire around 100 AD, body burials represent an absolute exception. Finds of Roman skeletons from this period are therefore extremely rare.”

All Male, All Young, All Killed in Battle

The burial bore no resemblance to an ordinary cemetery. Bodies were placed in as many as four layers without consistent orientation, many limbs intertwined, with no sediment layers separating them, indicating they entered the grave during a single event. The absence of scavenging marks suggests the dead were covered soon after burial.

Initial anthropological examination determined the individuals were exclusively male, predominantly between 20 and 30 years old, mostly taller than 1.7 meters, with few signs of infectious disease and notably good dental health. “From the arrangement of the skeletons, and because these are exclusively male remains, we can rule out that the site is connected to a military hospital or similar, or that a disease was the cause of death. The injuries on the bones are clearly attributable to combat,” said Michaela Binder, lead anthropologist at Novetus GmbH, the archaeological firm that carried out the excavation with Vienna City Archaeology.

An Unusual Concentration of Wounds

The skeletons themselves provide the clearest evidence of violent death. Researchers documented perimortem injuries caused by sharp weapons, blunt force, and projectiles, with sharp-force wounds especially common on the skull, particularly the face and frontal bones. But one detail stood out when researchers examined the overall pattern: roughly 40 percent of recorded injuries occurred on or around the pelvis, many consistent with projectile weapons such as lances and Roman pila.

A more detailed analysis presented by Sheridan Strang and Michaela Binder at the 25th European Meeting of the Paleopathology Association in Berlin in August 2026 reinforced that pattern. Their updated assessment identified trauma in 48 individuals, 85 percent of whom showed injuries inflicted around the time of death, with the pelvis again accounting for roughly 40 percent of recorded trauma. This doesn’t necessarily mean every blow specifically targeted the groin, as some reports have suggested. The more precise finding is that projectile injuries were unusually concentrated across the pelvic region, possibly because the lower torso was less protected by armor than the chest and upper body, though the skeletons alone can’t confirm exactly how the fighters were positioned or whether attackers deliberately aimed for that area.

Weapons That Confirm a Military Disaster

Objects recovered from the grave reinforce the battlefield interpretation: a dagger, several scales from a scale-armor cuirass, a cheek piece from a helmet, lance heads, and shoe nails. One of the lance heads was found still embedded in the sacrum of one individual. The iron dagger became the key find for dating and culturally placing the mass grave. “Its fragments were difficult to classify due to poor preservation. But in the X-ray image of the dagger sheath, characteristic Roman decorations are immediately recognizable. These are inlays made of silver wire, which allow the dagger to be dated to the period between the middle of the 1st and the beginning of the 2nd century AD,” explained Christoph Öllerer, deputy head of Vienna City Archaeology.

A Forgotten Battle on the Danube Frontier

Around the time these men died, the burial site lay roughly three kilometers southwest of the Danube, which formed Rome’s frontier with populations to the north, in largely uninhabited territory between two Roman military installations: the still-small camp at Vindobona about five kilometers to the northwest, and Ala Nova, near modern Schwechat, roughly four kilometers to the southeast. The grave sat not inside the Vindobona fortress itself, but within a militarized frontier landscape connecting Roman positions along the Danube.

The find represents the first direct physical evidence of a battle along the Danube frontier, previously known only through historical sources. Those sources describe repeated fighting between Roman forces and Germanic tribes near the end of the first century AD under Emperor Domitian, known as the Danube Wars of 86 to 96 AD, but no surviving text describes a battle at Hasenleitengasse specifically. “The mass grave in Simmering is the first physical evidence of combat from this period, and points to the location of a battle in the area of present-day Vienna. The event documented here could thus have been an occasion for expanding the previously small military base into the legionary camp of Vindobona, not even seven kilometers from the find site. Hasenleitengasse may thus reveal to us the beginning of Vienna’s urban history,” said Martin Mosser, an archaeologist with Vienna City Archaeology.

A Hypothesis, Not Yet a Confirmed History

That connection between the battle and Vindobona’s later expansion into a major legionary fortress remains a proposed historical link rather than a demonstrated fact. Researchers cannot yet securely tie the grave to Domitian’s Danube wars specifically, to a particular Germanic or Sarmatian attack, or to any named Roman campaign recorded in surviving texts.

What the burial does make clear is the scale of the crisis that produced it. Since cremation remained the standard funerary practice across the European Roman Empire during this period, the hurried burial of so many complete, uncremated bodies is highly unusual, and the chaotic arrangement suggests whoever buried the dead had neither the time nor resources for normal funerary rites.

What Comes Next

“The Vienna team is still just at the beginning of its research. Further investigations of the human skeletal remains and the recovered objects will be carried out as part of an international, interdisciplinary research project. In particular, DNA and isotope analyses give hope for exciting results regarding the origin and living conditions of the soldiers buried in Hasenleitengasse,” said Michaela Kronberger, curator at the Wien Museum. Researchers also plan further investigation of the surrounding landscape and ancient Danube channels.

Until that research is complete, Hasenleitengasse preserves the aftermath of a battle whose name and participants have vanished from written history, with the wounds on the dead beginning to tell a story that surviving Roman sources never recorded.
