the spire didn't exist after the French Revolution, it had been torn down and the church had been looted.
sometime in the 1830's people realized that they wanted it back and it took 20 years, but it was restored.
My quess about this is it was a false flag to blame the Muslims.
and as well to get some free money to replace a spire that probably needed replacement anyway.
PS: the Catholic Church doesn't own that property.
