Living Hope has submitted plans to convert a former church back into a place of worship.
Its planning application is for St Mary's Church on The Parade in Castletown.
The building was originally constructed and used as a parish church, but following its closure as a place of worship, it was converted to office accommodation and currently sits empty.
Living Hope wants to reopen it as a church for congregational meetings and events such as weddings and baptisms.
It said its application it would 'bring a vacant historic building back into active use while respecting its architectural and historic significance' and 'secures its long-term conservation through active use'.
The building was added to the Protected Buildings Register in 1984.
