On Thursday afternoon, some communities in Germany want to ring their church bells out of solidarity with the people in Ukraine.
European master builders had called for this.
In Cologne Cathedral, the bells should be heard for seven minutes, said a spokesman for the archdiocese.
Likewise the bells of the Mainz Cathedral.
But there was no central call from the Catholic German Bishops' Conference.
A DBK spokesman said that decisions would be made locally.
In the Evangelical Churches in Germany, too, it was said that the action was not a matter for the EKD, but for individual regional churches and communities.
One minute of bell ringing per day of war
The diocese of Aachen said that nationwide participation was not planned.
The diocese in Münster also referred to the parishes.
Initially, nothing was known about this in the Archdiocese of Paderborn and in the Diocese of Essen.
In Bavaria, for example, the Munich, Regensburg, Würzburg and Passau cathedrals are involved.
Some churches in Germany had already rung the bells for minutes the evening before.
The European Union of Cathedral Master Builders had called for the bells to be rung "every minute for one day of this senseless war" from 12 noon on Thursday.
"We, the community of those responsible for building the major cathedrals and cathedral churches in Europe from Norway to Malta and from Spain to Ukraine, do not want to remain silent about the war in Ukraine." The ringing is a sign of solidarity with the people who have been fighting since the feared for their lives during the Russian invasion of Ukraine.
"Europe is burning." The bells are also an expression of grief and prayer for all those affected by the war.
Historically, church bells have also often been rung for disasters, fires, and to warn people.
