What Happened to the Colosseum After the Games Ended?

The Colosseum’s active life as a spectacle venue lasted roughly 443 years, from its inauguration in AD 80 to the last recorded animal hunt in AD 523. Its afterlife — the 1,500 years since — has been longer and, in its own way, more eventful. Across the centuries following the last games, the amphitheatre served successively as commercial space, fortress, quarry, burial ground, Christian shrine, archaeological treasure and modern heritage icon. Each of these uses left physical traces that survive today, and the building visitors see is the cumulative product of this long, layered transformation. Understanding the afterlife is essential for reading the Colosseum as a historical document rather than an isolated ancient ruin.

The Afterlife Timeline

  • AD 523: last recorded venatio, under Theodoric
  • 6th–10th centuries: gradual abandonment and limited commercial use
  • 12th century: Frangipani family fortifies the structure as a castle
  • 1349: earthquake collapses the southern outer wall
  • 14th–17th centuries: systematic quarrying for Renaissance and Baroque construction
  • 1744: Pope Benedict XIV bans further quarrying
  • 1749: Benedict XIV consecrates the site as sacred to Christian martyrs
  • 19th–20th centuries: papal and state-led restoration and excavation
  • 1980: Colosseum added to UNESCO World Heritage List
  • 2013–present: Tod’s-funded conservation programme

Why Did the Games End?

Across the 4th and early 5th centuries, a combination of Christianisation, economic pressure and cultural change eroded the institutional framework that had sustained gladiatorial combat. Emperor Constantine restricted the practice in AD 325. Emperor Honorius banned it outright around AD 404 — traditionally after the martyrdom of the monk Telemachus. The last recorded Colosseum gladiator fight was AD 435; the last recorded animal hunt (venatio) was AD 523 under the Ostrogothic king Theodoric. See our article on The End of the Games for the full decline.

What Was the Early Medieval Colosseum?

The first several centuries after AD 523 are poorly documented. Rome itself contracted dramatically — from perhaps a million inhabitants at the empire’s peak to a few tens of thousands by the Gothic Wars’ aftermath — and the infrastructure that had sustained the Colosseum’s original function disappeared along with its population. Surviving references suggest the structure became progressively overgrown, filled with silt, and occupied at its edges by modest commercial activity. It was too large to disappear but too vast to maintain. An 8th-century Anglo-Saxon couplet captures its symbolic weight: “As long as the Colosseum stands, Rome will stand; when the Colosseum falls, Rome will fall; when Rome falls, the world will fall.”

How Did the Colosseum Become a Fortress?

During the 12th century, the powerful Frangipani family fortified the Colosseum and adjoining structures as a castle, one of several fortified strongpoints they used to dominate central Rome. Specific arches were walled up to create defensible chambers, and portions of the outer structure were adapted for residential and military use. Frangipani control ended after extended conflicts with rival families and the papacy, and the fortification was progressively dismantled as the political situation changed.

See The Medieval Colosseum for the full treatment of fortress and commercial uses.

What Did the 1349 Earthquake Do?

The earthquake of September 1349 collapsed the southern portion of the Colosseum’s outer ring wall. This single event is responsible for the building’s most visible feature today: the stark asymmetry between the intact northern façade (preserving the original four storeys) and the lower, truncated southern side (where the outer ring is gone and only the inner structural walls remain). The fallen stone was not cleared or restored; instead, it became a quarry resource for the next three centuries.

See The 1349 Earthquake for the full impact of the event on the Colosseum and other Roman monuments.

How Was the Colosseum Quarried?

Systematically, and on a massive scale. From the late medieval period through the early modern period, the Colosseum supplied building material for several of Rome’s most iconic structures: St Peter’s Basilica, Palazzo Venezia, Palazzo Farnese, Palazzo Barberini and numerous churches and minor buildings. Travertine blocks, marble facings, iron cramps, lead fittings and brick were all extracted and redeployed. The iron cramps were extracted for their metal value, producing the distinctive pockmarks visible across the surviving façade — every hole was once a cramp socket. The marble seating that had once tiered the interior was ground down for lime used as mortar.

Who Stopped the Destruction?

Pope Benedict XIV, through his 1744 quarrying ban and 1749 consecration of the site as sacred to Christian martyrs. The twin acts ended the systematic extraction of stone and established the building’s protected religious status, preventing further loss. Without these interventions, further quarrying would almost certainly have continued, and significantly less of the Colosseum might survive today. The current cross inside the amphitheatre, erected in 1926 on the sacred ground designated by Benedict XIV, remains the focal point of the annual Good Friday Stations of the Cross procession led by the Pope.

See Christian Martyrs at the Colosseum for the martyrdom tradition and its role in preservation.

How Was the Modern Colosseum Made?

Restoration began in earnest in the early 19th century under Pope Pius VII, who commissioned the first major modern intervention: a large buttress on the eastern end designed by Raffaele Stern to stabilise the outer wall. Further interventions followed under subsequent popes, with the principle established by Stern — that modern restoration should be distinguishable from ancient masonry rather than imitating it — becoming the enduring framework for subsequent work.

The 20th century saw major archaeological programmes, including the systematic excavation of the hypogeum under the Mussolini regime in the 1930s. The 21st century has brought the Tod’s-funded conservation programme, launched in 2013, which has included comprehensive cleaning of the façade, structural stabilisation of the hypogeum, and expanded visitor access including the 2023 extension of the arena floor reconstruction.

See Restoring the Colosseum for the full modern conservation history.

What Is the Colosseum Today?

The Colosseum is the most visited paid heritage site in the world, receiving roughly 7 million visitors per year. It is the icon of ancient Rome, the symbol of Italy on travel marketing and popular imagination worldwide, and a functioning archaeological park integrated with the Roman Forum and Palatine Hill. It hosts occasional ceremonial events — including the annual papal Via Crucis procession on Good Friday — but has not been used for regular performance since antiquity.

Its status as a World Heritage Site, conferred by UNESCO in 1980, marks it as part of the global heritage of humanity rather than merely Italian national property. The combination of ancient structure, medieval fortress traces, Renaissance quarrying scars, Christian devotional meaning and modern visitor infrastructure makes it a singular historical document: a building that has been used for almost every major Western institutional purpose across two thousand years.

Our Colosseum tours read the building as a layered document covering every era of its use, from the Flavian inauguration through the medieval fortress, Renaissance quarrying, Christian shrine and modern monument. Understanding the afterlife is as essential as understanding the ancient function: the Colosseum you see is the product of both.
