Colosseum
The Colosseum, the world's largest amphitheater, boasts impressive dimensions, measuring 189 meters in length, 156 meters in width, and towering at 50 meters in height. Selected as one of the New Seven Wonders of the World in 2007, this iconic structure is an architectural marvel. Ancient Romans harnessed substantial quantities of marble, approximately 100,000 cubic meters, transported by 200 bullock carts to the construction site. In addition, they utilized 1.1 million tons of concrete, stone, and brick. The modern reconstruction of the Colosseum would demand a staggering sum of around 39 million euros, or nearly 43 million dollars, underlining its historical and cultural significance.
