Ancient Norfolk tools to feature in exhibition Evidence that the first human beings to settle in Britain did so in Norfolk is to be the subject of a new exhibition opening at the Natural History Museum in London. Scientists now believe the humans walked from the European mainland and settled on what is now a caravan park in the village of Happisburgh. That was almost a million years ago when the East Anglian coast was joined to the continent and the Stone Age settlement was on what was then the River Thames estuary.
