A mysterious sign has appeared in Boxley but no one seems to know how it got there.

The placard is mounted on a wooden post and reads Canterbury to Glastonbury. Remnants of a white marble fireplace are scattered around it.

It is not known how it came to be placed on the North Downs Way, near Harp Farm at the top of Boxley Hill, but it is believed to have been created in the last 10 days.

It was discovered by Paul Fautley, of Beach Wood Road in Chatham, who was walking from Detling to Blue Bell Hill.

The 34-year-old said: “It is a pretty strange and random thing to come across here given that no obvious connection between the places immediately springs to mind.

“Someone must be keen for it to be there though.

“It is quite well put together and the parts of the fireplace are heavy. It can’t have been easy taking it over the gates along the footpath.

The sign is close to the Pilgrims Way, the path used by Christians to visit Canterbury, and a tentative link between the two places can be traced to a historical figure.

St Dunstan served as the Abbot of Glastonbury Abbey between 940 and 960 before becoming Archbishop of Canterbury until 978. Two centuries later his remains became the subject of a medieval fraud.

In 1188 the monks in Glastonbury claimed to have his remains alleging they were moved from Canterbury because of a Danish attack in 1018.

This attracted pilgrims to Somerset until the 16th century when it was disproved by Archbishop William Warham.

He opened a tomb in Canterbury in 1508 and found Dunstan’s relics still present, but the shrine were destroyed during the Reformation.

Kent County Council, the Friends of Boxley Warren and Boxley Parish Council said they have no idea how the sign could have got there.

The landowner was unavailable for comment.
