springs were generally regarded as sacred - the nature of the mysterious 'bubbling' spring at Alton Priors might add to this impression. add the yew. add the megaliths/holed stone. add the prehistoric Ridgeway connecting Priors with Avebury, Uffington (and Stonehenge?) ... there was another church in Wiltshire which seems to have attempted to dominate a natural, boggy spring site, this was at Swallowcliffe in Wiltshire. the church sank.
