Andrew Marr tells the story of the first empires which laid the foundations for the modern world. From the Assyrians to Alexander the Great, conquerors rampaged across the Middle East and vicious wars were fought all the way from China to the Mediterranean. But this time of chaos and destruction also brought enormous progress and inspired human development. In the Middle East, the Phoenicians invented the alphabet, and one of the most powerful ideas in world history emerged: the belief in just one God. In India, the Buddha offered a radical alternative to empire building - a way of living that had no place for violence or hierarchy and was open to everyone. Great thinkers from Socrates to Confucius proposed new ideas about how to rule more wisely and live in a better society. And in Greece, democracy was born - the greatest political experiment of all. But within just a few years, its future would be under threat from invasion by an empire in the east...

Of the Seven Wonders of the Ancient World, the Hanging Garden of Babylon is the most elusive of these constructions of classical antiquity. While traces have been found of the Great Pyramid of Gaza, the Temple of Artemis at Ephesus, the Statue of Zeus at Olympia, the Mausoleum of Halicarnassus, the Colossus of Rhodes and the Lighthouse of Alexandria, centuries of digging have turned up nothing about the lost gardens of Babylon – until now.
Why, in the nearly 3,000 years since the gardens were presumably built, has no archeological evidence ever been found to support their existence? Is the Hanging Garden of Babylon a myth or a mystery to be solved?
Travel with Dr. Stephanie Dalley of Oxford University’s Oriental Institute and author of The Mystery of the Hanging Garden of Babylon, to one of the most dangerous places on earth, as she sets out to answer these questions and prove not only that the gardens did exist, but also identify where they most likely were located, describe what they looked like and explain how they were constructed.
