This is St. Mary's Church Of Ireland Protestant church. This church was used because it looked more like a church and was quieter inside the grounds of Ashford Castle. This is where the holy water font was placed for the 'patty fingers' in the holy water scene. It's a bold sinful man you are, Sean Thornton, and who taught you to be playing patty fingers in the holy water. When they had finished filming the scene the crew forgot to return the font back to the Catholic Church.  When the congregation arrived for Sunday service, the church caretaker got into trouble for leaving the font outside their church. The lady in the picture is my wife Sandra.
