The £1.2 million repairs of St Thomas' Church has been completed this month, with the Catholic Dean going up the spire to bless the cross.
Work began in March after increasing concerns about the safety of the structure and fears that people passing by could be at serious risk of injury or even death if they were to be hit by debris caused by crumbling masonry.
The restoration project saw protective enclosures put around and over entrances to the island's biggest church, scaffold platforms on the spire, and debris netting installed.

The scaffolding is set to be removed before Christmas.
The church is still trying to raise £100,000 to finish the project.
