Prehistoric Ireland's Mega-Settlement Unearthed

Summary
- Co Wicklow hillfort identified as Ireland and Britain's largest prehistoric settlement.
- Site near Baltinglass is Ireland's earliest proto-town, predating Viking settlements.
- Excavations reveal over 600 potential roundhouse sites, indicating complex society.
A remarkable hillfort cluster in Co Wicklow, near Baltinglass, has been identified as the largest nucleated settlement in prehistoric Ireland and Britain. Researchers also contend it represents Ireland's earliest proto-town, dating back an estimated two millennia earlier than previously thought urban settlements on the island.
The extensive site, featuring up to 13 hilltop forts, spans from the early Neolithic to the late Bronze Age (c 3700-800 BC). New excavations and aerial surveys have revealed over 600 topographical anomalies consistent with prehistoric house platforms, suggesting a highly organized community.
Radiocarbon dating indicates occupation from the Late Bronze Age (c 1210-780 BC) into the Early Iron Age (c 750-400 BC). This discovery challenges prior understanding of prehistoric settlement, highlighting advanced social complexity, community cohesion, and regional importance not previously recognized, and has won the Prehistoric Society's James Dyer prize for 2025.
