About three hundred yards from Graystown Abbey, we came upon these ruins of pre-reformation character. The east and west gables stand at their original height but the south wall is almost gone and the north wall is beginning to crumble. It is known as ‘Yellow Church’ pronounced as Cill Bhuidhe and stands in ruins on the townsland of Ballintogher. The building was constructed of limestone, lime sand and mortar and measures thirty two feet seven inches in length by sixteen feet seven inches in breadth. The side walls are nine feet in height and three feet two inches in thickness. On the east gable there is a window of chiselled limestone pointed to a curve, five feet ten inches from the present surface of the ground inside where it is quadrangular and of masonwork. This is three feet four inches broad at the bottom and five feet eleven inches high. On the outside it is four feet five inches high and seven and three quarter inches broad. On the south wall, within seven feet two inches to the east gable, is placed a window four feet from the ground. KIlboy church is dedicated to The Three Kings.
It is now opened at the top,the wall being knocked down. Outside the door on the ground, lies a square of limestone whose sides measure two feet, being eleven inches thick with figures of the Blessed Virgin represented with Our Saviour in her lap after being taken down from the cross, chiselled on it. The figure is in the upper part, embedded in the stone. There has been no burial here for many years.
