It was meant to be a temporary exhibit, a demonstration of French engineering acumen at the Paris World's Fair. But to Parisians, the tower, designed by the brash, young Gustave Eiffel, came to stand for much more--revolution, innovation and a soaring spirit.

A symbol of freedom and democracy towering above the New York Harbor, she has welcomed the tired, the poor, and the huddled masses into America for more than 100 years. Authoritative and richly detailed, the Statue of Liberty explores the remarkable steps leading up to its creation from the initial struggles to find adequate funding to its celebratory centennial restoration project. Discover the engineering marvel of the statue's internal framework designed by Gustave Eiffel and see rare footage and archival photos which document the radical methods the French devised to shape the massive sculpture and transport their incredible creation to American shores. A testament to human ingenuity, freedom, and hope, Modern Marvels is proud to present the fascinating story behind the famous Mother of Exiles.

The incredible tale of how Gutzon Borglum created the world's largest sculpture by carving the faces of four U.S. presidents (George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln) into the Black Hills of South Dakota. The four figures carved in stone pay tribute to the first 150 years of American history. The hour chronicles the "swiveled pointer" that Borglum put in each president's "head," and how workmen hung like spiders 6,000 feet above the ground to blast away 450,000 tons of rock.

Journey underground and backstage at the technological marvel that is Walt Disney World. Enter a make-believe world spanning some 27,000 acres, brought to life by cutting-edge technology. What was once Florida swampland now boasts the world's largest theme park. the ride technology ranges from space-age centrifuges to enhanced motion vehicles powered by 3,000 PSI of hydraulic pressure. And hundreds of audio animatronics brought to life through the power of pneumatics, hydraulics, and electrical systems. Walt Disney World is made up of four separate theme parks, each with its own innovations: the 107-acre Magic Kingdom, Epcot, Disney-MGM Studios, and Disney's Animal Kingdom. the four parks are all part of a megaplex of a resort. Twice the size of Manhattan, it was the final vision and crowning achievement of a man who spent more than 40 years pushing the limits of technology to create entertainment magic: Walt Disney.

Since the turn of the 20th century, designers have competed to build them faster, taller, and steeper. But as technology pushes the envelope with flips, weightlessness, and more g-force than a jet, how many thrills can the human body take?

Rising from a stretch of desert with nothing but remoteness to recommend it, Las Vegas became a glittering wonderland for dreamers. We'll take a look at the forces that made Las Vegas a place unlike any on earth.

The task was monumental: Build the world's largest dam in the middle of the desert, and tame the river that carved the Grand Canyon--all in seven years! When the Hoover Dam was completed in 1935, it was the largest dam in the world. We'll reveal how this engineering wonder of the world was conceived and built.
