The Assyrian Gallery at the British Museum
This film examines a world wonder so elusive that most people have decided it must be mythical. Centuries of digging have turned up nothing — but the searchers were digging in the wrong place. Now, this film proves that the spectacular Hanging Gardens of Babylon did exist, shows where they were, what they looked like and how they were constructed.
Secrets of the Dead: The Lost Gardens of Babylon, Tuesday at 9 p.m. on PBS 6.
