Britain’s ancient pubs (or are they?)

The pub guide on this website has a category called Ancient Pubs. When I added it I was thinking about the very oldest pubs and I’d assumed that it would include those dating from maybe the 1100s up to the 1400s. Like most people, I was ready to believe claims made by pubs like “dates back to the twelfth century”, or “over 800 years old”. And why not, as these claims are repeated without question in dozens of pub guides from the early 1900s to the present day.
