While I don't have an exhaustive list of repairs to the Colosseum with specific dates, I can provide a general overview of major restoration efforts that have taken place over the years:

1. Ancient Repairs:

• The Colosseum underwent various repairs during ancient Roman times, addressing damages caused by natural disasters and wear and tear from events.

2. Medieval and Renaissance Periods:

• The Colosseum was repurposed and modified during the medieval and Renaissance periods. Some repairs were likely carried out to adapt the structure to new uses.

3. 18th Century:

• Pope Benedict XIV initiated some restoration work in the 18th century, focusing on stabilizing the structure and preventing further decay.

4. 19th Century:

• Extensive restoration efforts were undertaken by Carlo Fea in the early 19th century, aiming to preserve the Colosseum's architectural integrity.

5. 20th Century:

• Restoration projects were conducted in the early 20th century, including efforts to address structural issues and combat pollution-related damage.

6. 21st Century:

• Ongoing maintenance and conservation projects continue into the 21st century, utilizing modern technologies and materials to preserve the Colosseum for future generations.

For a detailed and accurate chronological list with specific dates, it's recommended to refer to official records from organizations responsible for the conservation of the Colosseum, such as the Italian Ministry of Cultural Heritage and Activities or relevant archaeological and preservation authorities. These entities would likely have comprehensive documentation on the history of repairs and restoration efforts
