Here is an interesting bit of history. And, its not negative, unlike so many news stories.
*A relic venerated by Christians as the Crown of Thorns worn by Jesus was paraded on Friday in Paris from Notre Dame Cathedral to the dazzling Gothic chapel built to house it in the 13th century. The relic rarely leaves the cathedral and its return to the Sainte Chapelle, a medieval gem known for its soaring stained glass windows, and the Mass said to celebrate it were the first such events there since the 1789 French Revolution.
The French Catholic Church staged the procession, the start of a weekend of ceremonies, to mark the 800th anninversary of the birth of Saint Louis, who as King Louis IX bought the relic in 1239 from Baldwin II, the cash-strapped Latin Emperor of Constantinople, and brought it to Paris. Installed in Sainte Chapelle, which was finished in 1248, it stayed there until the Revolution.*
There are videos, which are in French, but might be worth a look.
