The major repairs to the Church of the Immaculate Conception could take up to five years to fully complete and the development has been labelled "the biggest project ever undertaken in the town or parish".
Tallow Church Renovation Committee representatives said: "Our parish church of the Immaculate Conception requires major renovation, and a committee has been formed, to ensure the necessary repairs are carried out and the funds raised to conduct this very important work."
The costs for the first phase of the development amounts to €110,000.
Representatives added that if the project is not carried out, the church could become a health and safety risk to the public or could end up closed.
The committee also expressed the importance of the church to the community, saying: "Our Church is two hundred years old and is a one-off church that other parishes would love to call their own. It has several stained-glass windows and beautiful wall mosaics painted by Italian artists sent to Ireland by the Vatican two centuries ago. It is the most important building in our town and parish and its importance cannot be underestimated.
"It is the place where we were baptized, received our first holy communion, were confirmed, married and where we will spend our last few hours. Our church has the adjoining well-kept graveyard where generations of our families are buried and where many come to visit the church and graves of their loved ones."
Donations from the public will be the main source of income to finance the project according to the committee.
"We are now requesting our parishioners everywhere to donate to this particularly important project to protect our parish church from further decay as your donation will be the main source of income to finance the project."
