St Thomas's Church in St Helier is undergoing £1.3 million worth of repairs to its spire.
The cost of the work to the 19th Century structure is being crowdfunded, with generous islanders donating the money to get the landmark building repaired.
Specialist Steeplejacks have come over from the UK to take on the 20 week project to repair the fifteen foot iron cross on the top and the surrounding granite stonework.
Jersey's Roman Catholic Dean says work on the spire had to be done due to its critical state.
It hasn't been examined properly for a good many years and a lot of the stonework, was found to be in need of re-pointing and inside the spire we were able to see there was a lot of repointing needing to be done. The type of work that you need to do on a building like this happens once in a lifetime but it would happen to be now wouldn't it.
Canon Dominic Golding told ITV News that they have almost reached their £1.3 million target.
Jersey's Roman Catholic Dean says it is a "staggering amount of money", but it has to be done ensure the future of the building.
I was asked, do you need the spire, can't you just get rid of it? But I would argue it is an iconic worth, which enables people to think upwards and I think that's needed at a time like this to think about life's higher things and leaving aside the fact it is one of Jersey's prominent buildings and I think we have a responsibility to future generations to look after it.
The work began at the start of the year and is expected to be complete by early November.
