"Tullaroan", a parish, in the barony of Cranagh, county of Kilkenny, and province of Leinster, 7 miles (N.W.) from Kilkenny; containing 3650 inhabitants, of which number 182 are in the village. Tullaroan formed part of the extensive territories of Raymond le Gros, Earl Strongbow's companion in arms. He fixed his principal residence at Courtstown, in this parish, whence the head of the family was in after times sometimes styled Baron of Tullaroan or of Courtstown, and the surrounding land were often distinguished by the name of Grace's parish. Its eastern boubdary lies within 4 miles of the city of Kilkenny, joining the liberties; its western is the small river Munster, which borders it for three miles, forming the demarcation between Kilkenny and Tipperary: its extent is about six miles from east to west and five miles from north to south. Three-fourths of the parish consist of hills of considerable height, enclosing a fertile and spacious vale of pasture and meadow-ground.
It is a rectory and vicarage, in the diocese of Ossory, forming part of the union of Callan. In the R. C. divisions it is part of the union or district of Freshford: the chapel is on the townland of Brith. There are six private schools, in which about 280 children receive instruction. There is scarcely a townland in which some vestige of remote antiquity cannot be traced. One of the most perfect raths is at Courtstown: it is composed of a large moated enclosure encompassing a smaller: on the same townland are two others of inferior dimensions: others of very large size are on the lands of Rathely-Grace, and near the site of the old parish church. The ruins of Courtstown castle, ..., are now reduced to little more than an outline of the foundations. About a half mile eastward of the castle are the ruins of Tullaroan church and Grace's chapel, both founded by members of the Grace family; the former are of small extent and present little to attract attention; the latter, which is an offset from the church, is entered by a curiously decorated ogee gateway. In the village are two ornamented stone crosses in a perfect state; a throd, now mutilated, is on the roadside near Bonnetstown.
