However, it has undergone periods of rediscovery and re-evaluation throughout history:
* Ancient Times: The Colosseum was built in 80 AD and was actively used for gladiatorial contests, animal hunts, and public executions for centuries. It was a major landmark of the Roman Empire.
* Medieval Period: After the fall of the Roman Empire, the Colosseum was gradually abandoned and fell into disrepair. It was used as a source of building materials, with some of its stones being used for churches and other structures in Rome.
* Renaissance and Beyond: During the Renaissance, the Colosseum began to be recognized as a significant monument of Roman history. It was gradually cleared of debris and its importance was recognized.
* 19th and 20th Centuries: The Colosseum was extensively restored and conserved in the 19th and 20th centuries, solidifying its status as a major tourist destination and symbol of Rome.
So, while the Colosseum was never truly "discovered" in the traditional sense, its significance was rediscovered and its importance re-established throughout history.
