Visitors to Manchester Cathedral are being urged to unite in song to mark the 10th anniversary of the IRA attack on the city centre.
The IRA bomb devastated a large section of the city centre
A service is planned in memory of the blast, and clerics hope it will form the focal point as the city unites to remember the events of 15 June 1996.
The cathedral's lead roof was lifted three inches by the bomb, and three stained glass windows were shattered.
Two hundred people were injured in the explosion but there were no fatalities.
The bomb destroyed a large area of the city centre near the cathedral, but a warning allowed the area to be evacuated.
Damage put at £700m was caused, including the destruction of Marks and Spencer and parts of the Arndale Centre.
The service is intended to give thanks for the spirit of Manchester and for the subsequent rebuilding of the city.
An extensive rebuilding programme took place after the blast, transforming the area with new architecture and designer shops.
The Dean of Manchester Cathedral, the Very Reverend Rogers Govender, said: " The bomb was not good for Manchester, but I think the people of the city have ensured something good has come out of it."
The service takes place at Manchester Cathedral on 15 June at 1100 BST.
