Not guilty m'lud - never been to Cliff Pypard. I have seen puddingstones built into the corner foundations of churches in Essex, Herts and Bucks. Puddingstone is a very hard conglomerate that is found in these non stoney areas. Building stone for these churches had to be brought in from elsewhere - some from Kent (ragstone) some from Normandy. I have often wondered if the puddingstones were entirely practical ie they are hard and available - or if there was a ritual association. I am a bit anti-ritual at present, but that stance got a bit of a shock just recently when Baza pointed out that the Stansted Airport sarsen stone was excavated from a pit in a Bronze Age village. Why was it deliberately buried in a pit if not for ritual?
As some of you will know, I am interested in attempting to verify or refute, the existence of a long distance neolithic trade route from Grimes Graves marked by puddingstone way marks.
