“Built in 8 Years. Lasted 2000.” “The Roman Colosseum wasn’t just built—it was engineered. Using 100,000 m³ of stone, volcanic ash concrete, and 60,000 workers, Rome created a stadium with elevators, trap doors, and even a retractable sunshade—still standing 2,000 years later.” #Colosseum #AncientRome #WorldWonders #HistoryFacts #EngineeringMarvel #Architecture #Rome #ancientengineering #civilengineering #timeless
