Dan Cruickshank visits 40 countries and six continents to reveal awe-inspiring temples, towers, ruins, monuments and artefacts. Some of the treasures he has chosen are undisputed wonders of the world, others are not as well-known but just as awe-inspiring, and some are surprising, even shocking.
Along the way, he visits some of the most mysterious places on Earth, and the most dramatic. He comes face to face with the legacies of great ancient civilisations, and cultures which are clinging onto survival in the modern age. He learns something about human aspirations, about the secrets of life and death, and ultimately about himself.
