Archeologists from Queens University Belfast have described an area in County Wicklow as “the largest nucleated settlement identified in prehistoric Ireland and Britain.” Their findings are reshaping the established understanding of Bronze Age and Iron Age social organization in ancient Ireland and challenging assumptions about settlement patterns in prehistoric Europe.

Antiquity magazine first reported the discovery in a Nov. 18, 2025, article. Since the first of the year other scientific journals and the popular press have featured additional stories.

The study area at the south-western edge of the Wicklow Mountains is about 45 miles south of Dublin city. It is known as the Baltinglass hillfort cluster. It includes up to 13 large hilltop enclosures which contain up to 600 suspected house platforms. The site shows signs of continuous settlement from the Early Neolithic through to the Bronze Age, between 3700 to 800 BC.

Fáilte Ireland (the National Tourism Development Authority) in 2015 launched the “Ireland’s Ancient East” tourism initiative to promote “over 5,000 years of history hidden amidst these lush landscapes, winding rivers and glorious gardens” of the region. This finding should add to the mystique.
