VILLEDIEU-LES-POELES, France (AP) — Nine enormous, new bronze bells are on their way to Paris to help the medieval Notre Dame Cathedral rediscover its historical harmony.

The bells, named after saints and prominent Catholic figures, will be on display at the cathedral from Saturday through Feb. 25. Then they will be hoisted to its iconic twin towers, where they will replace older bells that had become discordant.

The new bells are scheduled to ring for the first time March 23, in time for Palm Sunday and Easter week.
