Vandalization by the huguenots

The last time, it was calvinists who vandalized Notre Dame

The French Religion Wars were a 36-year period of conflict between Roman Catholics and Huguenots (Reformed/Calvinists Protestants), from 1562 to 1598.

Supposedly, in 1548, during the war, huguenots vandalized the Notre Dame Cathedral in an effort to rid it of idols and images of worship. It is a well documented event in newspaper articles, like the ones below:
