The map point marked Gefrin refers to the archaeological landscape at Yeavering, in Northumberland, not to the modern museum building. The ancient site lies in open countryside near the River Glen and the Cheviot Hills. Ad Gefrin, the visitor attraction, is in Wooler, about four miles away. Keeping the two locations distinct is essential: the palace field is an archaeological landscape, while the Wooler centre provides galleries, a reconstructed great-hall experience, a distillery and a bistro.
Yeavering is widely identified with Ad Gefrin, the royal township described by the eighth-century historian Bede. The Gefrin Trust relates Bede’s account of a royal visit in 627, when Paulinus, the Christian missionary associated with King Edwin’s court, taught and baptised people in the nearby River Glen. This written account connects the landscape to a major episode in the Christianisation of Northumbria, though the riverbank should not be confused with a surviving ceremonial structure.
