Archaeologists have uncovered a substantial stratified deposit within an early Roman well, providing new insights into the development of the Roman city of Colonia Ulpia Traiana in Xanten, Germany.
The well, reaching a depth of approximately seven metres, has been dated to the mid-1st century AD, prior to the formal establishment of Colonia Ulpia Traiana under Trajan. This early date makes the feature particularly important for reconstructing initial phases of Roman occupation in the region, when infrastructure and urban organisation were still developing.
Construction Technique and Site Formation
The shaft was constructed from at least two wooden barrels, each approximately 2 meters tall. The reuse of the barrels as structural elements is well attested in Roman contexts and illustrates the efficient use of raw materials in frontier environments.
The preservation of the structure has made very detailed documentation possible concerning the building and subsequent depositional history. Excavations were carried out in multiple field seasons under carefully controlled stratigraphic conditions. At the very bottom of the well, archaeologists found waterlogged deposits with low oxygen levels, conditions that significantly enhanced the preservation of organic materials.
Artefactual Assemblage and Deposition
The recovered assemblage includes a range of domestic items, notably a finely crafted bone spoon, fragments of high-quality glass vessels, and a substantial number of ceramic containers such as jugs and storage pots. Many ceramic pieces were found largely intact, suggesting minimal disturbance after deposition.
The assemblage’s morphology suggests that the well was repurposed after it ceased functioning as a water resource, becoming a refuse pit. This is a documented practice in Roman settlements and often results in well-preserved, contextually coherent assemblages.
It is significant, in particular, for organic remains (i.e. wood and bone) that are rarely found in archaeological settings. Their survival in this context offers additional opportunities for deep study of material culture and everyday operations.
Research Significance
The well is a closed archaeological environment and has significant analytical value. Subsequent specialty studies will explore ceramic typologies, use-wear traces, and the material composition of the glass finds to better understand production processes and long-distance trade networks in the Roman world.
Collectively, the findings support a picture of early settlement in the Lower Rhine during the transitional phase prior to the formal urbanisation of Colonia Ulpia Traiana, further enhancing our overall understanding of the early period.
The absence of extensive later rebuilding at Xanten further strengthens the site’s importance as a well-preserved record of early Roman provincial life.
