The story of Britain starts at the end of the last ice age. In the cold, Britain emptied of people. With so much ocean water frozen in glaciers, sea level was lower, and Britain was connected to the rest of Europe. As the world warmed, they walked back until rising waters severed the land bridge.

Around 3800 B.C. the first large monuments appeared — rectangular mounds known as long barrows that served as burial chambers.
