8 March-7 Jan. This exhibition uses installations, models and artefacts to shed light on how the Colosseum was used in the centuries after the fall of the Roman empire.
The show highlights the Colosseum's hidden history, including recently-discovered evidence of a 12th-century fortress, which was built into the ruins by the powerful Frangipane family but collapsed in the 1349 earthquake.
The exhibition recounts how the ancient monument was widely pillaged of stone and how its internal spaces were used for stables, slaughterhouses and workshops during the mediaeval era.
Located on the first level of the Colosseum, the show also reveals how the arena was completely overgrown by the time the Grand Tourists arrived from Britain and northern Europe in the 18th century.
