How Did They Build That? Series 1

Across the globe, radical architects, ingenious engineers, and skilled builders are creating structures so outrageous, they defy logic…and often even gravity. From a Manhattan skyscraper that looks like a Jenga tower to a Singapore glass dome big enough to house a mountain to a high rise in Italy with a built-in forest, we examine the world's most extraordinary buildings, bridges, and lifts, reveal their design secrets, and discover the incredible stories of their construction as we try to answer the question How Did They Build That?

Part 4 Viaducts and Hotels

How did engineering innovation allow for a bridge to stand 1,000 feet above the river it crosses? How did engineers flip the rule book upside down to build a hotel nestled into a 300-foot-deep abandoned quarry? And what happens when you attempt to build a forest in the sky in the middle of a city? Join us as we visit the Millau Viaduct in France, the Wonderland Hotel near Shanghai, and the Bosco Verticale in Milan and reveal the incredible stories and brilliant minds behind these remarkable structures.
