Lanyon Quoit, a Neolithic dolmen in Cornwall, England

Time has altered the land around it, but Lanyon Quoit in Cornwall, England, still commands attention.

Built in the Neolithic period, 'The Giant's Table' offers a rare chance to consider how early settlers marked their presence.

Formed by upright stones holding a massive capstone of about 13,000 kilograms, the monument likely served as a communal burial chamber.
