U.S. churches to ring bells for reopening of Notre Dame Cathedral. As the Notre Dame Cathedral in Paris prepares to reopen on Dec. 7, U.S. bishops are calling on local American churches to show their solidarity with the Church’s “eldest daughter.” Five years ago, a devastating fire broke out across the timber roof and 315-foot-tall oak spire of the beloved 12th-century French cathedral. Restoration to the structure began with a two-year cleaning process followed by a $760 million reconstruction project.In a social media post, the United States Catholic Conference of Bishops (USCCB) wrote that as the cathedral reopens its doors, “local churches in the U.S. are invited to peal their bells in a gesture of unity.”
