Country Life Trending: The views and the history are equally breathtaking at High Point, a striking new house in an ancient setting. Nobody really knows which is the oldest road in Britain, but when discussion turns to that subject then one name is certain to pop up: The Ridgeway. This 87-mile route from Overton Hill, near Avebury, to Ivinghoe Beacon, just outside Leighton Buzzard, has been walked for at least four millennia, and probably even more. As it trails through the countryside it passes by equally ancient sites: the stone circle at Avebury, the White Horse at Uffington and Waylands Smithy, a burial site that pre-dates Stonehenge by 1,000 years.
