The UK’s sweltering summer has already been marked by four major heatwaves, making it one of the hottest seasons on record. But the relentless dry weather has brought with it an unexpected archaeological bonus.
Hidden Buildings Emerging From the Ground
At two National Trust estates, soaring temperatures and dry conditions have revealed parch marks across lawns and parkland. These marks, which appear as patterns of dried grass, expose the outlines of long-lost underground structures dating back centuries.
The phenomenon occurs because grass above buried stone walls and foundations dries out faster than surrounding soil, effectively drawing maps of hidden buildings for archaeologists and visitors to see.
Mottisfont Priory’s Lost History
One of the most striking discoveries has been made at Mottisfont, a former Augustinian Priory near Romsey, Hampshire. Archaeologists have been able to trace the remains of monastery buildings that were abandoned in the 1700s, during a major remodelling of the estate.
The outlines, usually invisible to the naked eye, have been brought back into view by this summer’s drought conditions.
Why This Matters
Experts say these parch marks provide invaluable insight into Britain’s hidden past. Unlike expensive digs, nature itself is helping to uncover history without excavation, giving archaeologists clues about how historic estates were once designed and lived in.
A Silver Lining to a Scorching Summer
While the record-breaking heat has brought challenges across the country, from drought warnings to increased wildfire risk, at least one positive has emerged: centuries-old secrets are being revealed beneath the grass of Britain’s historic estates.
This story is developing as archaeologists continue to study the sites.
