The four stones at the top of one of the Clent Hills are not an ancient pagan temple but a Victorian folly, erected by Lord Lyttleton of Hagley Hall to enliven the view. You'd think the huge obelisk on nearby Wychbury Hill and the mock Greek Temple of Theseus would have been enough.
Anyway, it's a little known fact that from time a mysterious fifth stone appears, with holes in it like shortbread. Bet Lyttleton didn't see that coming.
More details? Try this for speculation that he built the stones to annoy a neighbour...
