Notre Dame Cathedral in Paris is getting its bells back, just in time for the medieval landmark’s re-opening following a devastating fire in 2019.

A convoy of trucks bearing eight restored bells — the heaviest of which weighs more than four tons — pulled into the huge worksite surrounding the monument on Thursday on an island in the Seine River.

They are being blessed in a special ceremony inside the cathedral before being hoisted to hang in its twin towers for the December 8 re-opening to the public.

Cathedral Rector Olivier Ribadeau Dumas, wearing a hardhat as he prepared to enter the cathedral and bless the bells, called them “a sign that the cathedral will again resonate, and that its voice will be heard again. A sign of the call to prayer, and a sign of coming together”.

The bells will be raised one by one and tested out, but they will not ring in full until the day of the re-opening, said Philippe Jost, overseeing the massive Notre Dame reconstruction project.

He called the bells’ arrival “a very beautiful symbol of the cathedral’s rebirth”.

While construction on the cathedral started in the 12th century, the bronze bells damaged in the fire are from the 21st century.

They were built according to historical tradition to replace older bells that had become discordant, to mark the monument’s 850th anniversary.

The cathedral’s roof and spire, which collapsed in the fire, have been replaced, and scaffolding is being gradually removed from the site.
