An ancient relic said to have been worn by Jesus Christ at his crucifixion has returned to the Notre-Dame Cathedral, five years after the relic was saved from a fire that devastated the church.

The Crown of Thorns – comprised of a circle of rushes encased in a crystal and gold tube – was brought back to the cathedral in a ceremony overseen by the Archbishop of Paris, Laurent Ulrich.

The crown was acquired by King Louis IX of France in Constantinople in 1239 for 135,000 livres – nearly half France’s annual expenditure at the time.

Initially kept at the Sainte-Chapelle, it was moved to Notre-Dame’s treasury in 1806 – until a massive fire in 2019 ripped through the 850-year-old building.

Firefighters and police officers formed a human chain to rescue the relic and other historic artefacts in the cathedral.

The crown, which has been kept at the Louvre Museum while the famed cathedral underwent extensive renovation, has been placed in a newly built reliquary to replace the one from 1806.

The ceremony marking its return was led by a procession attended by members of the Equestrian Order of the Holy Sepulcher – a Catholic order of knighthood.

The Crown of Thorns will be displayed for the public from 10 January, French media reports.

The cathedral reopened its doors to the public on 8 December, after extensive restorations works involving an estimated 2,000 craftspeople costing a reported €700m (£582m).

Its reopening ceremony was attended by world leaders. In a speech at the event, French President Emmanuel Macron said of the restoration: “We must treasure this lesson of fragility, humility and will”.
