royston cave

looking up into the roof of the bottle shaped man made cave under royston in herts. covered in mediaeval religious carvings. one of these holes in the roof was the original entrance, so this was no shrine or chapel. the current passage was cut in georgian times. there is no sign of there having been an upper floor; claims that one stood on posts are ridiculous and impractical, as the obvious means of support would have been to cut joist holes into the soft chalk. so access had always to be via rope or ladder; if long term use was considered then something easier would have been sorted out. I lean more and more to its having been a prison, and the rustic carvings the work of bored prisoners of the c15 or c16.
