A recent archaeological investigation in the city of Leuven, Belgium, has revealed a remarkably preserved Roman-era wooden water pipe. Conducted during pre-construction work for a new student residence on Brusselsestraat, this discovery offers new insights into the city’s distant past and the infrastructure used in ancient times.
Well-Preserved Wooden Pipe System Found Underground
The excavation uncovered a wooden water pipeline stretching approximately 20 to 30 meters in length. Each segment of the pipe, about 1.75 meters long, was crafted from hollowed-out tree trunks connected end to end. Located around four meters below the surface, the pipeline was found in a relatively intact condition.
Experts explain that the pipe’s preservation is due to the local soil conditions. Situated in a valley with waterlogged and oxygen-poor soil, the environment prevented the usual decomposition of organic material such as wood.

Estimated to Date Back to the 1st–3rd Century CE
Based on the stratigraphic layer in which the pipe was found, archaeologists estimate that it dates from the 1st to 3rd century CE — during the Roman occupation of the region. Further analysis, including dendrochronology (tree-ring dating), will help determine the pipeline’s exact age.
Additional Roman and Medieval Artifacts Discovered
The site also yielded other archaeological remains, including fragments of pottery, roof tiles, septic pits, and Roman coins. These findings suggest continuous or repeated occupation of the site from Roman times through the Middle Ages, offering a broader view of the area’s historical significance.
Conservation and Public Display Plans Underway
The wooden pipe and accompanying artifacts will undergo detailed conservation work. After analysis and preservation, they are expected to be displayed in a museum or exhibition space, allowing the public to engage with Leuven’s historical layers more directly.
