Altheim-Weirading villa rustica

The Altheim-Weirading villa rustica is a Roman farm estate (villa rustica) in the hamlet of Weirading, in the Kiriberg district northeast of the town of Altheim in the Innviertel region of Upper Austria, occupied from about 80 to 240 CE¹. It is one of three villa rustica sites excavated in the municipality of Altheim, alongside Simetsberg and Wagham, and it is by far the largest, with a main building 100 meters long, a bath building of roughly 350 square meters, and a 50-meter covered walkway joining the two¹.

Location and Roman context

The estate stood in the Innviertel, the hilly farmland between the Inn river and the Danube limes in the Roman province of Noricum. The surrounding country around Altheim, which lies 363 m above sea level, consists of rolling land on glacial gravels and loess-covered terraces, under oak-hornbeam woodland naturally and today farmed intensively⁵.

A villa rustica, in the sense the Roman agronomists gave the term, was a working farm rather than a mere country house. Columella, writing in the late 1st century BCE, described the villa as divided into the pars urbana where the owner and his household lived, the pars rustica housing laborers, animals, and tools, and the pars fructuaria for processing and storing the harvest⁶. The Altheim estates served the self-sufficiency of a large household and produced surpluses for nearby towns and for forts on the limes³. The fertile land along the Inn supplied Roman troops stationed on the Danube frontier as well as the cities of Ovilava (Wels) and Iuvavum (Salzburg), which is why the regional museum presents the area as the granary of the Roman Empire in Upper Austria⁷.

Three villae rusticae are proven by excavation in the municipality of Altheim, at Simetsberg, Weirading, and Wagham, roughly 2.8 to 3 km apart, and four more can be inferred in the immediate surroundings; in total seven estate sites are attested in the nearer area up to Wildenau³.

Discovery and excavation

Roman finds came to light at Weirading early in the twentieth century. The first investigation, a small excavation in 1913/14, was carried out by Hugo von Preen (1854–1941), a local researcher from Braunau am Inn, in the area of the bath building; it produced no recorded plant remains⁵. An early twentieth-century report also noted Roman rubble and brick fragments surfacing on the Kiriberg, on a rectangular parcel measuring 350 by 100 Roman feet⁸.

Modern research. Systematic work began with geophysical prospection of the terrain, which mapped the villa's full extent before any digging; when excavation followed in a selected area, all the wall remains predicted by the survey were indeed found³. Resistivity mapping and ground-penetrating radar at the site were presented internationally, including a resistivity map showing the main building and the nearby bath and a 3D visualization based on the prospection results⁹. The University of Vienna's prospection projects at Altheim-Weirading ran in 1995, 1996, and 1997 under Wolfgang Neubauer, an archaeologist at the University of Vienna specializing in archaeological-geophysical prospection¹⁰.

The full campaign at Weirading lasted from 1994 to 1998 and produced 28 archaeobotanical samples; the excavated areas comprised building I with 72 m² and building II with about 620 m²⁵. The findings were published in full in Die archäologischen Forschungen in Altheim 1991–1998 (Vienna, 2006), the report of the excavations conducted by the Institute of Classical Archaeology of the University of Vienna at the three Altheim estates¹¹.

The estate and its buildings

The Weirading villa stands out among the Altheim estates for its size. A covered porticus about 50 m long connected the main house with the bath building, a layout described as a unique finding in the province of Noricum⁴. The bath itself was large for a villa rustica: published accounts give its area as about 350 m², nearly 300 m²⁴, or dimensions of 30 by 15 m¹², but all agree it was an unusually generous bathing complex for a farmstead.

The buildings were richly appointed even though little survives above floor level. Soil erosion and the mechanization of agriculture, especially from the twentieth century onward, destroyed much of the roughly 1,800-year-old fabric, leaving rubble below the original floor level. Mosaic tesserae, fragments of painted wall plaster, a rare stucco molding profile, roof tiles, and the remains of floor and wall heating systems nevertheless document the former quality of the buildings⁷. The finds assemblage includes pottery, glass, a coin, bricks, stucco, and window glass¹³. Neither the Weirading nor the Simetsberg excavation showed evidence of a large fire catastrophe, so the estate does not appear to have ended in a destructive blaze⁵.

Comparison with Simetsberg. The contrast between the two excavated estates shows a settlement hierarchy. At Simetsberg, the main building measured 12 by 14 m, the bath 8.5 by 10 m, and a probable storage tower 7.5 m on a side³.

Plant remains and dating

The 28 archaeobotanical samples from the 1994–1998 excavations came mostly from the bath building, where 8 of its 18 documented rooms were sampled, with further samples from the dwelling, building I⁵. The report dates the estate to the period from the mid-1st to the mid-3rd century CE, slightly broader than the ca. 80–240 CE range given for the site's occupation¹^•⁵. At Simetsberg, the corresponding finds, including sigillata ware, glass, fine ware, fibulae, and everyday pottery, point to use between the late 1st and the early 3rd century, about four generations of occupation³.

The site today

After the excavations and documentation were complete, the foundations were reburied. The site, about 3 km northeast of the Römermuseum Altheim on the slope of the Geinberger Wald, is freely accessible year-round and largely barrier-free; visitors see the reconstructed bath foundations, a cutaway showing a Roman hypocaust heating system, information panels updated in 2018, and audio recordings²^•⁴.

In 2018 a new geophysical survey of the villa by ZAMG Archeo Prospections produced fresh results, and an ideal reconstruction of the estate based on them can be viewed in a stereoscopy viewer at the site, with the model in the Römermuseum Altheim⁷^•¹⁴. The finds from all three Altheim villas are displayed in the Römermuseum Altheim in the Ochzethaus, whose permanent exhibition, redesigned in 2018 under the theme "Innviertel, the granary of the Roman Empire in Upper Austria", presents agriculture, livestock, and daily life on a villa rustica²^•¹⁵.
