Scientists working on the scorched interior of Notre-Dame de Paris have found iron was used in the cathedral’s construction in the mid-12th century.

The findings were made possible—ironically—by the devastating fire that swept through the famous cathedral in April 2019 during planned renovations. The fire destroyed most of the church’s roof and prompted unprecedented repair work on the building, which is expected to reopen in 2024.
