Modern Marvels - Season 8 Episode 18 The Colosseum
7.90 44 minutes Modern Marvels brings the heart of the Roman Empire back to life through the rich history of this famous amphitheater. Built in 70 AD, the Roman Colosseum seated 80,000 people, boasted a retractable roof, underground staging devices, marble seating, and lavish decorations. To this day, it serves as the prototype for the modern stadium. The complexity of its construction, the beauty of its architecture, and the functionality of its original design made the Colosseum the perfect place for massive crowds to congregate for the bloody spectacles it was built to contain.
