Exploring the Enigma of the Hanging Gardens

More than 2,000 years ago, someone sat down and wrote a travel bucket list for the ancient world — suggesting must-see places that we now call The Seven Wonders of the World. It was kind of a Lonely Planet guide of its time, and included the Pyramid of Giza, the Hanging Gardens of Babylon, the lighthouse of Alexandria, and the Temple of Artemis, among others. Historian Bettany Hughes brings monuments and archaeological discoveries back to life in her book, The Seven Wonders of the Ancient World.
