On St John’s Day, 24 June 1717, four London Lodges, which had existed for some time, came together at the Goose and Gridiron Tavern in St Paul’s Churchyard, declared themselves a Grand Lodge and elected Anthony Sayer as their first Grand Master. This was the first Grand Lodge in the world. This was the founding of the Premier Grand Lodge, the first of its kind anywhere in the world and the origins of the United Grand Lodge of England.
