Episode Summary

Engineering the Impossible: Colosseum
In its prime, the Colosseum was a venue for gladiators to fight to the death, but today, the arena lives on as one of the grandest and most spectacular megastructures in the world. Constructed in the absence of electricity, power tools or earth-moving equipment, it reveals an architectural process that rivals today's modern methods. Two thousand years ago, its creators pioneered the use of building materials and techniques that are still with us today-including concrete, bricks, drainage systems and production lines-to build a structure that could hold more than 50,000 people and allow them to exit in just 30 minutes. Discover the story behind the building of one of the world's most iconic structures and see why it is truly a monument to the strength and power of human imagination.moreless
