<p>Stand at the Ness of Brodgar on Scotland's Orkney Islands and several iconic Stone Age structures are within easy view, forming the core of a World Heritage site called the Heart of Neolithic Orkney.

The site’s extraordinary planning, craftsmanship, and thousand-year history are helping rewrite our entire understanding of Neolithic Britain.</p>
