During the early 19th-century a plaque was erected at the site that read: "On July XXII AD MCCCCIIII OWEN GLENDWR ascended this Tree to reconnoitre, on his march to Shrewsbury, to join the daring Hotspur, against King Henry IV; but, finding his friends were defeated, returned from this spot into Wales" (the date and year stated here, 22 July 1404, are not those of the actual battle).
