The heatwave has been described as “critical” in the discovery of a henge, or circular enclosure in the Unesco World Heritage Site close to Newgrange in Co Meath.
The henge, which could measure up to 200m in diameter, is believed to have been built some 500 years after Newgrange, which dates from 3,000 BC.
