Pubs called the George quite frequently refer to St George, the patron saint of England, who is depicted with a white horse and a shield with a red cross on a white background.
There is a legend of St George killing a dragon as on the George Hotel sign above and there are plenty of inns named the George and Dragon. These two look quite chummy to me.
The George and Pilgrim’s in Glastonbury was originally a guest house for pilgrims visiting the Benedictine shrine nearby but when Henry VIII dissolved the abbey it was turned into an inn. Its original name was The George. The Pilgrim’s was added to the name at a later date.
There have also been six kings of the name of George and some inn signs show one or other of them but I have yet to photograph any of them yet.
I should point out that the poor quality of many of the inn sign photos is because they are taken through the window of a moving car.
