The rotary at the land’s end is the site of the First Landing Marker, which rises from an apron of commemorative and memorial paving stones. It was originally placed here in 1917 by members of the Research Club, an antiquarian-minded group of Mayflower descendants that had been founded seven years earlier at 84 Bradford Street. They based their dubious assertion about the landing spot on a map in an 1865 edition of A Relation or Journal of the Beginning and Proceedings of the English Plantation Settled at Plymouth in New England, by Certain English Adventurers, Both Merchants, and Others, published in London in 1622 and better known as Mourt’s Relation, after the typographically corrupted name of the author of its preface: George Morton.
