8th Century CE Rock Cut Graves and St. Patrick’s Chapel, Horsham, Lancashire.

Quote from the original post - "This rocky headland possesses distinctive rock cut graves and the ruins of an 8th century chapel that was extended in the 10th century. A hogback stone in the nearby church suggests this was a site visited by Vikings or at least influenced by them."
