  Reopening of Notre-Dame de Paris

  en.wikipedia.org· Added Sep 14, 2026· 48% of score

  Wikipedia's^[1] "Reopening of Notre-Dame de Paris" article confirms the cathedral "reopened on 7 December 2024 following completion of the restoration work," but the retrieved content does not address the pin's separate claim about exterior/flying-buttress work continuing toward a 2030 completion, so it only weakly supports this estimated pin.

  After Accelerated but Incomplete Reconstruction, Notre-Dame de Paris Reopens to the Public

  architecturalrecord.com· Published Dec 1, 2024· 4% of score

  Architectural Record reports that while Notre-Dame reopened to the public in December 2024, full restoration of the exterior (scaffolding, flying buttresses, sacristy) will not be complete until 2028 at the earliest, consistent with the pin's later 'restoration complete' event being distinct from the 2024 reopening.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
