According to Paul Devereux and Ian Thomson’s ‘Ley Guide’, Winchester lies on an 11 mile ley from Tidbury Ring to a barrow beyond St.Catherine’s Hill. There was an Iron Age hillfort on this hill and in the 12th Century a small chapel dedicated to St.Catherine was built, of which slight traces remain. The Castle Hall in nearby Winchester has lots of Arthurian legends attached to it, which I’m afraid to say do bore me.
