Saint Fin Barre's Cathedral will hold it's traditional Civic Choral Eucharist for the first time since 2019.
Historically, the service is held on Saint Patrick's Day morning.
The celebration is open to the public and is also usually attended by members of the City Council, Defence Forces and voluntary organisations.
Bishop Colton is this year's celebrant and the City's Lord Mayor will read the First Reading.
The Civic Choral Eucharist will begin at quarter past nine on the morning of the 17th.
