70 WONDERS OF THE MODERN WORLD looks at major architectural and engineering feats of the 20th century. Architects have created homes that vary from the functional white cubes of Modernism to glittering palaces such as Hearst Castle and the Sultan of Brunei's Palace, while city skylines have become dominated by the skyscraper. Buildings as diverse as the Louvre Pyramid, the Sydney Opera House and the Lloyds Building in London have surprised and thrilled the public. Monuments such as the Atomium in Brussels and the Moscow Rocket Museum have been built to celebrate the milestones of human progress, while others, such as Mount Rushmore and the Vietnam Memorial, proclaim the indomitability of the human spirit. Thanks to human ingenuity and skill, at the end of the century skyscrapers reach higher and bridges farther than ever before; huge dams, such as the Aswan Dam and Itaipii, harness the power of mighty rivers, and a giant solar oven captures the energy of the Sun.
