Giant and imposing, they may be the best adjectives to describe the fantastic Colosseum. Up close, you can feel the energy of that place and transport yourself to another time, when that amphitheater, still in operation, received thousands of Romans on weekends to watch the playful activities that took place in its arena. Many emperors walked the corridors of that building, and many slaves, gladiators, and wildlife died in the arena in bygone ages. A symbol of pride for Italians and humanity, the Colosseum has a curious and dense history that begins even before its construction in the days of Emperor Nero. I invite you to immerse yourself in this rich history and travel with me to this wonder of ancient times that is still alive and powerful in the heart of Rome. This book features dozens of photographs of this ancient building, with details of its internal and external structures, as well as explanatory texts with clear and objective language about curiosities and historical facts. The book still has many photographs and information about two buildings adjacent to the Colosseum, the Arch of Constantine and Temple of Venus and Rome, which are also ancient buildings that deserve to be presented to you, dear reader. I hope after reading this book you will feel part of the vibrant energy of that place and realize that this wonder of ancient times is among the most visited man-made monuments on the planet.
