The world watched in horror Monday night while flames tore through the Notre Dame Cathedral in Paris. As fire consumed the roof and toppled its iconic central spire, it seemed as though the historic church could be lost forever — but it’s possible, thanks to cutting-edge imagining technology, that all hope may not be lost.

Thanks to the meticulous work of Vassar College’s art historian Andrew Tallon, every exquisite detail and mysterious clue to the building’s 13th-century construction was recorded in a digital archive in 2015 using laser imaging.

These records have revolutionized our understanding of how the spectacular building was built — and could provide a template for how Paris could rebuild.
