Britain’s Ancient Tracks with Tony Robinson

(Channel 4, 8pm-9pm)

Tony follows the Ridgeway from the Wiltshire Downs, through Berkshire and Oxfordshire, finally arriving on the banks of the Thames. Along the way, he visits a world-famous stone circle and explores an ancient burial chamber that is older than the pyramids, follows in the tracks of Celtic chariots, and discovers the story behind a white horse.
