I want to know the answer to the following question:
What pub holds the Guinness World Record as the oldest in England?
All the background I'm provided with is that "Likewise, The Nags Head in Burntwood, Staffordshire only dates back to the 16th century, but there has been a pub on the site since at least 1086, as it is mentioned in the Domesday Book.". Is that enough to answer the question?
