10 Things Invented Way Earlier Than You’d Expect

9. The Origins of Modern Architecture: The Roman Concrete

Roman concrete, or opus caementicium, is one of the most enduring legacies of ancient engineering. Developed by the Romans over 2,000 years ago, this remarkable building material has withstood the test of time, as evidenced by structures like the Pantheon and the Colosseum. Unlike modern concrete, which often degrades over time, Roman concrete is known for its durability and resilience. The secret lies in its unique composition, which includes volcanic ash that reacts with lime to create a strong, long-lasting bond. This ancient innovation not only revolutionized construction techniques in the Roman Empire but also influenced the development of modern architecture. The principles of Roman concrete continue to inspire contemporary engineers and architects seeking sustainable and durable building solutions. The enduring legacy of Roman concrete underscores the timeless nature of architectural innovation and its impact on the built environment.
