A Roman road about seven metres wide and a structure believed to be a parade ground wall have emerged beneath Caerleon Comprehensive School in Newport. What began as a watching brief during construction has now become a full archaeological excavation, with coins, ceramics and other Roman material also being recorded.Image credits : Newport City Council
The Discovery
The unexpected remains were found during construction work for a new full-size sports hall, upgraded changing facilities and modern teaching spaces at Caerleon Comprehensive School.
Archaeologists from Heneb, the Trust for Welsh Archaeology, were initially monitoring the building work. Instead of simply observing construction, however, the team began finding substantial archaeological deposits.
Stone deposits eventually developed into recognisable structural remains.
The largest discoveries so far are what archaeologists believe to be a parade ground wall and a road system approximately seven metres wide.
The road is particularly interesting because the excavation has allowed researchers to extend their understanding of a route already known from the nearby Broadway playing fields.
Martin Tuck, site supervisor for Heneb at the school, said the excavation had grown from a watching brief into a full-scale archaeological investigation because of the material being uncovered.
Although the work remains ongoing, the material identified so far appears to be Roman.
The discovery was described as surprising despite Caerleon's exceptionally strong Roman archaeological record.
The settlement is home to the remains of the Roman amphitheatre associated with the legionary fortress of Isca, as well as the nearby Roman Fortress and Baths.
The newly discovered remains therefore sit within an already important Roman landscape.
What Archaeologists Found
The archaeological team has uncovered several categories of Roman material.
The most substantial features are the suspected parade ground wall and the broad road system.
The road measures approximately seven metres across, providing a significant piece of infrastructure that may help researchers understand movement through Roman Caerleon.
Excavators have also recovered smaller objects, including coins and ceramic fragments.
These finds are being carefully documented alongside the larger architectural remains.
The excavation is using photography, written records, drone photography and scale drawings to create a detailed record of the site.
The approach is designed to preserve information about the location and relationships of the discoveries before construction proceeds.
Tuck said archaeologists have been able to extend their knowledge of the road from the Broadway playing fields towards the school, where related material may continue.
That possibility could make the surrounding archaeological area particularly important for understanding the organisation of Roman Caerleon.
The researchers have not yet completed the excavation, meaning the full extent of the Roman remains remains unknown.
Could the road beneath the school be part of a larger Roman route that archaeologists have only partially traced?
Further excavation and comparison with earlier archaeological investigations may provide an answer.
Historical Background
Caerleon has one of Wales' most significant Roman archaeological landscapes.
The area contains the remains of the Roman legionary fortress of Isca and its associated amphitheatre, built almost 2,000 years ago.
The amphitheatre provides evidence for the military and public life associated with the Roman settlement.
Another major feature is the Roman Fortress and Baths, which form part of the protected archaeological landscape.
The amphitheatre itself was uncovered in 1926 after approximately 30,000 tonnes of soil were removed from the surface.
It subsequently became a protected historical landmark.
Despite this long history of archaeological investigation, substantial Roman remains have now emerged in an area being developed for a modern school.
The latest excavation is also being compared with archaeological work undertaken in Caerleon during the 1950s and 1960s.
Heneb archaeologists plan to revisit those earlier investigations to determine whether the newly discovered features can be connected with remains documented decades ago.
That comparison could help place the school excavation within the wider Roman layout.
Scientific Analysis
The excavation is being documented according to standard archaeological procedures.
Photography and written records are being combined with drone photography and measured scale drawings. This creates a detailed record of the structures, surfaces and artefacts uncovered during the investigation.
The archaeological context of the finds will be particularly important.
A road, for example, can provide information about how different parts of the Roman settlement were connected. Its relationship with the previously known route from the Broadway playing fields may reveal whether the newly uncovered section forms part of a longer system.
The suspected parade ground wall could also provide evidence about the organisation of military space.
However, its precise function remains an interpretation at this stage. The excavation team has described it as what is believed to be a parade ground wall, rather than presenting that identification as conclusively established.
Coins and ceramics may provide additional chronological information and could help establish which phases of Roman activity are represented.
Researchers will also compare the new evidence with records from the excavations carried out in Caerleon during the mid-20th century.
Why This Discovery Matters
The significance of the discovery comes partly from its location.
Caerleon was already known for major Roman remains, yet the school excavation is demonstrating that archaeological evidence continues beyond the best-known monuments.
The road could extend an existing understanding of movement through the Roman settlement, while the suspected parade ground wall may add information about how military spaces were organised.
The smaller finds are valuable for a different reason.
Coins and ceramics can provide evidence about everyday activity and chronology, helping researchers move beyond monumental architecture to investigate how people lived and used the settlement.
The discovery also illustrates how archaeological evidence can survive beneath modern developments.
The remains were identified not during a conventional research excavation, but while construction work was taking place for new school facilities.
What began as a watching brief has therefore developed into a much more substantial investigation.
What's Next?
Excavation and recording will continue at the school.
Archaeologists will carefully document additional structures and artefacts while examining whether the Roman road continues beyond the area already exposed.
The team also intends to return to archaeological work conducted at Caerleon during the 1950s and 1960s.
Comparing those earlier records with the new evidence could establish whether features identified decades ago are connected to the structures now being uncovered.
Further analysis of coins, ceramics and other small finds may also help establish the chronology and character of activity at the site.
Because the excavation is still underway, the complete layout and function of the newly identified Roman remains cannot yet be determined.
The investigation may ultimately reveal whether the suspected parade ground and road formed part of a larger military complex.
Conclusion
The discovery beneath Caerleon Comprehensive School has transformed a routine archaeological watching brief into a full-scale excavation.
A suspected Roman parade ground wall, a road approximately seven metres wide, coins, ceramics and other material are adding new evidence to the already extensive archaeological record of Caerleon.
The road's possible continuation from the Broadway playing fields towards the school could be especially valuable for understanding Roman movement through the settlement.
For now, archaeologists are continuing to record the evidence and compare it with earlier excavations.
The work may show that even in one of Wales' best-known Roman landscapes, important pieces of the ancient settlement remain hidden beneath the modern town.
