The outer wall of the Colosseum, also known as the „façade,” is one of the most iconic and recognizable elements of this ancient amphitheater. Originally standing at a height of nearly 50 meters, the wall was constructed using travertine stone and designed with a series of arches on four levels, each adorned with columns of different architectural orders: Doric, Ionic, and Corinthian. The outer wall not only provided structural support to the immense arena but also served as a stunning visual symbol of the power and grandeur of the Roman Empire. Though parts of it have been damaged over the centuries due to earthquakes and stone quarrying, what remains of the outer wall still conveys the impressive scale and architectural ingenuity of ancient Rome. Today, visitors can marvel at its size, craftsmanship, and the enduring beauty that has made it a timeless symbol of the city.
