With their low ceilings, timber beams and roaring fires, many of England’s inns lay claim to being the oldest in the land and to have been visited by Vikings and Saxons.But an archaeologist working for Historic England says not one of the more than two dozen pubs that make this claim is being accurate.While many claim origins dating back 1,000 years, Dr James Wright, a buildings archaeologist, said it was difficult to verify whether any pubs were built and used as inns or ale houses and kept in continuous use prior to the 1400s.After painstaking investigation, including tree-ring dating on the wooden beams of pubs – a process known as dendrochronology – Wright named the George Inn, of Norton St Philip, Somerset, which has been in continuous use as an inn since around 1430-1432, as the oldest pub in England.Inside the George, set up in the 14th century by the monks of Hinton Priory.

Prior to that, it was speculated to date to 1030, 770 and 672,” he said. “There does not seem to be a basis in reality for any of those claims. Instead, the building started as a monastic dovecote, built around 1400.

The earliest date when we can say for sure it was active as a public house is the first decade of the 19th century.”Many of the pubs claiming to be the oldest say they were mentioned in the Domesday Book, but the historian said: “There are no pubs mentioned – at all – in the Domesday Book, so any pub claiming to be in it is having you on.”Wright added: “The claims are likely to originate less in folklore and more in canny marketing strategies by landlords, tenants, breweries and pub companies. The claims potentially rely upon the public not being aware of how to accurately date historic buildings.”The King’s Head in Shrewsbury is a serious contender for the title of one of England’s oldest pubs.

His methodology was to determine that it was purpose-built as a public house, that it had been in continuous service and that there was archaeological, archival or dendrochronological evidence for the existence of significant primary fabric remaining from the original construction.“I did consider buildings which had been converted and others which had periodically changed in land use,” he said. “Even with those taken into consideration, there are only about 12 to 16 genuine contenders which have been doing trade since the medieval period.

Of these, the oldest date to the 14th and 15th centuries.”Revealed: Wright’s list of oldest pubs George Inn, Norton St Philip, Somerset: late 14th century and 1430-32. Bull Hotel, Ludlow, Shropshire: 14th and 15th centuries.
