On January 18, 2020, the Archbishop’s Palace of the Archdiocese of Ho Chi Minh City decided to stop ringing the old bells at the cathedral as they became damaged.
The new melody consists of 25 brass bells produced by Perrot GmbH & Co.KG of Germany.
Four of the new bells were inscribed with the names of four archbishops since 1960, while the remainders have the names of contributors who have helped restore the cathedral since 2015.
The ongoing restoration began in late 2015 after the cathedral turned 135 on April 5 the same year. The project is being carried out by the Belgium-based Monument Group and is expected to be completed in 2027.
