It was discovered last fall during construction work to build a stormwater retention basin near the town of Wolkertshofen. Because the site was known to have remains of settlements and burials going back to the Neolithic, the work was overseen by archaeologists in collaboration with the Bavarian State Office for Monument Preservation.

The quality of the construction, the Mediterranean style of the stone base of the walls, and the location alongside the Via Claudia Augusta, the major Roman road that crossed the Alps linking the Po valley of northern Italy to Augusta Vindelicorum (present-day Augsburg), indicates this was a burial tumulus from the Roman period. The remains of a large Roman villa rustica (country estate) were unearthed less than two miles away in 1993, which also supports the identification of the structure as a funerary mound since the wealthy landowners would have been able to afford such high-end construction.

Raetia encompassed parts of modern Switzerland, Northern Italy, Austria, southern Germany and all of Liechtenstein, where there was a long tradition of burial mounds going back to the Bronze Age. In Raetia, prehistoric burial mounds were often reused for secondary burials in the Iron Age. Roman tumuli began to appear in the Augsburg area in the 1st century, and may have been a deliberate return to the area’s pre-Roman cultural tradition of burial mound construction, but tumuli with stone ring walls of monumental proportions are connected to Roman funerary custom rather than the earlier Celtic practices.
Its size, quality and preservation make the Wolkertshofen burial mound unique in the region, shedding new light on the funerary and memorial practices of Roman Raetia.
