Unknown Roman Settlement Discovered Under Welsh Housing Development
Archaeologists uncovered a 2,000-year-old industrial site in Mancot before planned housing construction.
1Unexpected Archaeological Discovery
In December 2025, archaeologists from Heneb discovered a previously unknown Roman settlement in Mancot, Wales. The site was identified during a pre-construction survey for a 300-home development called Gladstone Grange. This discovery is significant because the location was entirely absent from historical records, offering new insights into Roman-era activity in the region.
2Phased Settlement Evolution
Excavations revealed a Romano-British industrial community featuring complex plot boundaries and drainage systems. The site evolved in phases, beginning with timber houses potentially dating to the late Iron Age. By the third century AD, these structures were replaced by elongated, semi-rectangular buildings, with remains likely extending beneath the modern village of Big Mancot.
3Evidence of Local Craftsmanship
The site yielded a large collection of metalwork, including various brooches and a lead spindle whorl. Notably, researchers found casting molds, suggesting inhabitants manufactured these items on-site. A denarius coin minted in AD 192 during the reign of Emperor Commodus was also recovered, helping to establish a clear timeline for the settlement's occupation.
4Industrial Supply Network Links
Heneb researchers believe the Mancot inhabitants operated within a wider industrial supply network. This network likely served local populations and the nearby Roman legionary fortress of Deva Victrix in Chester. The Twentieth Legion occupied this fortress for over 300 years, making the proximity of the Mancot site a crucial piece of regional history.
5Challenging Historical Narratives
Historically, the land surrounding Chester was often described as a largely undeveloped hinterland. The discovery at Mancot challenges this view, suggesting Roman Wales was far more complex and interconnected than previously understood. This finding aligns with other industrial evidence found in North Wales, such as lead smelting sites and Roman road networks.
6Comparative Regional Context
Other sites in North Wales provide context for the Mancot findings. At Pentre Ffwrndan, workers smelted lead ore, while Prestatyn hosted timber workshops for bronze and iron smiths between AD 90 and 160. These sites, combined with the Mancot discovery, illustrate a sophisticated, integrated industrial landscape across the region during the Roman occupation.
7Ongoing Analysis and Conservation
While fieldwork at the Gladstone Grange plot has concluded, the recovered artifacts remain under laboratory analysis and conservation. Heneb has not yet released a total count of the brooches or coins found. Once conservation is complete, the items will be transferred to Flintshire Museum Services for future public display, though no date is set.
8Future Research Implications
The discovery highlights the importance of archaeological monitoring before modern development. Although the link to the Chester fortress remains a probability rather than a confirmed fact, the site provides a foundation for future study. Researchers must now determine the full extent of the settlement, which likely continues under the existing residential area.
