The Holy Thorn Reliquary in the British Museum has a single thorn that is just visible in the center.

The Rothschild reliquary that is perhaps the most elaborate of all, was created for the highly flamboyant brother of a French king around 1400. It seems strange for it to be displayed just like any other artifact in the British Museum when in its day this was the most revered object in private hands. Countless visitors wander unknowingly past the reliquary today, while in centuries past the faithful would have approached it on their knees.

Saint and King Louis IX was responsible for bringing the Crown of Thorns to France, as commemorated in this stained-glass window showing the king carrying a very green relic.

The crown of King Wenceslas in St Vitus’ Cathedral in Prague contains a holy thorn in the cross at the top.

Legend has it that whoever wears the crown will die within a year, which is what happened to Reinhard Heydrich.

Soon after its arrival in France, the Crown of Thorns had been kept in a church whose existence was a red rag to the already incensed revolutionaries of Paris.

The ultimate reliquary for the Crown of Thorns was La Sainte Chapelle, purpose built in the 13th century to house this and other sacred relics. Oddly, the revolutionaries respected the relic's integrity more than the kings who were so keen to make an impression. For this reason, no parts of it have gone missing since 1790.
