Standing majestically for centuries, the world's great pyramids have long inspired and mystified scholars; leading experts and historians explore the engineering genius that created some of the largest structures on the planet.

Built of stone and glass, persistence and prayer, gothic cathedrals are an epiphany of imagination and an articulation of joy; featured are such masterpieces as Chartres, Notre Dame and the National Cathedral in Washington D.C.

During the depths of the Depression, it was FDR's greatest triumph: a massive public works project that took a 40,000 square mile, disaster-prone river basin, and turned it into a model of industrial progress.

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.

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.

Built with the pioneering use of steel-wire support cables, the Brooklyn Bridge became an instant symbol of American pride; rare photographs and behind-the-scenes stories recall the politics, the struggles, and the tragedies that made it possible.

More than 50 years after its construction, the Golden Gate remains one of the world's great engineering marvels. It took 25-million man-hours and 80,000 miles of cable to complete; the cost in human life proved even greater.

The Panama Canal is thought to be the 7th wonder of the modern world, but now to fit the worlds' growing fleet of super ships, the Panama Canal is getting a completely revamped; a look inside the billion dollar Panama Canal Expansion Project.
