Even in the bright winter sunshine the dark, craggy entrance to Robin Hood’s cave at Creswell Crags on the border of Derbyshire and Nottinghamshire has an ominous sense of foreboding.
But for hundreds of years the cavern has held an even more sinister secret.
It was once believed by locals to be the entrance to the underworld, which held demons so terrifying that locals regularly carved protective ‘witch marks’ onto the walls to bind its evil occupants inside.
Until recently, experts at the caves believed the marks were simply graffiti but a chance encounter shortly before Halloween last year has led to a complete reevaluation of the site.
