What does it take to safeguard the world's most famous places? How do you maintain buildings that are thousands of years old? How do you secure a historical structure that contains millions of dollars worth of artefacts?

Ancient Impossible reveals how many of today’s technological achievements were actually developed centuries ago. Colossal monuments, impossible feats of engineering and technologies so precise they defy reinvention–the ancient world was far more advanced than we ever imagined. We’ll travel through history to reveal a radically different picture of the past, with innovations so far ahead of their time; they’re still in use today. New science uncovers a lost world more like our own than we ever suspected, and reveals how modern technology has its blueprint in the ancient world.

Britain is criss-crossed by a network of ancient trackways that have been travelled for over 5000 years. Tony Robinson returns for a new series to explore more of these remarkable routes and the mysteries and legends that surround them.
