The abbey’s choir holds what is alleged to be the tomb of Arthur and Guinevere. The discovery of two bodies in an ancient cemetery outside the abbey in 1191 was taken to confirm that here was, indeed, the mystic Avalon, and they were transferred here in 1278. Elsewhere in the grounds, the fourteenth-century abbot’s kitchen is the only monastic building to survive intact, with four huge corner fireplaces and a great central lantern above. Behind the main entrance to the grounds, look out for the thorn tree that is supposedly a descendant of the original Glastonbury Thorn said to have sprouted from the staff of Joseph of Arimathea. Big-name concerts and drama productions take place in the abbey grounds in summer – check the website for details.
