A recently discovered large hilltop settlement could challenge the theory that the Vikings built the first towns in Ireland, a researcher has said.
Dr Dirk Brandherm and his colleagues have identified more than 600 suspected houses in the Brusselstown Ring making it, to date, the largest nucleated settlement ever discovered in the entirety of prehistoric Britain and Ireland.
The settlement, which is thought to have emerged at about 1200 BC (the Late Bronze Age), is located within a region called the Baltinglass Hillfort Cluster in the south-western edge of the Wicklow Mountains.
It is among the 13 large hilltop enclosures spread across the mountain range where there are structures dating back to the Neolithic period and Early Bronze Age.
The findings were recently published within Antiquity, a peer-reviewed journal of world archaeology.
The study states: Given its exceptional size, density of occupation and architectural complexity, Brusselstown Ring represents a unique case within both the Baltinglass hillfort cluster and more widely within the Atlantic Archipelago.
Survey work has been conducted over the last two decades but researchers believed critical questions about the date, development and function of both the enclosing elements and the internal settlement remain unanswered. Therefore, researchers initiated test excavations in 2024.
The available evidence indicates their occupation mainly during the Late Bronze Age, with continued use or reuse of some house platforms in the Early Iron Age. This makes Brusselstown Ring the largest nucleated settlement agglomeration by far in prehistoric Ireland and Britain, the study highlighted.
Dr Brandherm, a reader in prehistoric archaeology at Queen's University Belfast, said the Brusselstown Ring is significant due to the large number and the concentration of roundhouses in one spot.
The image archaeologists had is that during the Bronze Age the settlement structure was based on small hamlets (one to five dwellings) and there were no villages or towns. In 2002, about 74 roundhouses dating back to the Bronze Age were discovered during the Corrstown excavation in Northern Ireland.
The researcher said Corrstown was the first village from that era, but the Brusselstown Ring is a different ball game altogether.
The Brusselstown Ring discovery questions the idea that the first towns on the island of Ireland were founded by the Vikings, according to the researcher.
Because if you've got more than 600 roundhouses, and potentially a large stone built cistern, that's no longer a village, Dr Brandherm told BBC News NI.
We're talking a proto-town of sorts, and that's 2000 years before the Vikings.
There are two widely spaced ramparts (defensive walls) encompassing the enclosure. These ramparts do not only enclose its own summit but also that of the nearby Spinas Hill One - meaning it is one of the very few hillforts in Europe to span more than a single hill.
A stone-lined, flat-floored chamber was also discovered near one of the trenches at the site. Dr Brandherm described it as being boat-shaped and slightly larger than a round house. It appeared to have been fed by a stream from an outcrop uphill, and archaeologists believe it may have been a water cistern to store fresh water.
If confirmed, the discovery of this cistern is a first in Ireland, as there are similar structures from the Bronze Age and the Iron Age in France and Spain.
Dr Brandherm said, based on the data that we presently have all the house platforms would appear to date to the same period. The larger houses are about 11-12m in diameter, with smaller ones being 4-5 meters diameter, which raises questions about social stratification within the community.
Future work at Brusselstown will focus on confirming the nature and the date of the potential cistern, identifying structural features of the prehistoric roundhouses and establishing the nature and chronology of the enclosing elements.
