What Happened to the Roman Colosseum?
The Roman Colosseum, one of the most iconic symbols of ancient Rome, is often admired for its grandeur and historical significance. However, many people wonder why it appears incomplete today, with only part of the structure still standing. What happened to the other half of this architectural marvel? Over the centuries, the Colosseum has endured earthquakes, repurposing, and even looting. Though battered and weathered, it stands as a testament to Rome’s enduring legacy.
Let’s break down the fascinating story of how the Colosseum was slowly dismantled by both nature and human hands, and how it has managed to survive despite it all.
The Colosseum was originally a complete oval, a marvel of engineering that could seat tens of thousands of spectators. But over the centuries, the mighty amphitheater began to suffer from the forces of nature, particularly from devastating earthquakes. One of the most significant quakes struck in 847, causing the southern side of the Colosseum to collapse. The damage didn’t stop there—another major earthquake hit in 1349, taking down even more of the south side.
By the time the 1703 quake rolled around, the Colosseum had already lost much of its original form. This quake caused further destruction, including the loss of two or three arches on the second ring. Over time, the once-complete structure became the partial ruin we see today, with its southern side being the most impacted by these seismic events.But the Colosseum wasn’t just a victim of natural disasters—it was also systematically dismantled by humans during the medieval period. Pieces of its marble and decorative elements were scavenged to build new structures across Rome.
The Colosseum effectively became a quarry, with its materials being repurposed to construct churches, palaces, and even the iconic St. Peter’s Basilica. As the city evolved, the Colosseum found itself serving new, unexpected purposes. Spaces under its vaults were rented out for housing and workshops, and noble families such as the Frangipani and Annibaldi turned it into a fortress, contributing further to its decay.
Despite the centuries of wear and tear, both from natural forces and human interference, the Colosseum remains a powerful symbol of ancient Rome’s glory. It’s a survivor, a monument that has endured the trials of history, standing as a reminder of the empire’s greatness and resilience.
