Time Team S12E13 - Animal Farm - Hanslope, Milton Keynes

An unusual horse bit, some posh finds and carved stonework lead Time Team on a search for a Norman hunting lodge in Northamptonshire. But it isn't long before the lodge's massive stone walls begin to look a little less impressive, and, under the forensic trowels of the diggers, the lodge shrinks in every direction. But royal forests were fiercely protected by the Norman nobility; why are there buildings here at all? Does the Domesday Book hold a clue? It seems as if this area was home to an extraordinary number of pigs... Have the Team come across one of the very first factory farms?
