Norman exile, early 13th century
Jordan De Courcy and the castle
The village is named for Jordan De Courcy, a kinsman of John De Courcy, the Norman conqueror of Ulster. After John fell at Downpatrick the family lost ground, and Jordan was exiled to Exeter; he returned to Ireland and built a fortress on this site early in the thirteenth century. In the 1240s the surrounding territory owed the service of two knights to Geoffrey de Geneville, lord of Trim, so this was a working frontier of the medieval lordship. The standing ruin you see today - two flanking towers, a fragment of bawn, and a tall circular stair-turret that locals compare to the Wonderful Barn in Kildare - sits beside a bridge on the River Mongagh. It is on private land next to a modern house, heavily overgrown, and there is no formal access. The honest advice is to view it from the road.
Planter family, 16th-17th century
The Giffords
The family most associated with Castlejordan castle are the Giffords, who acquired the lands during the Tudor and Stuart confiscations rather than building the place. By the time of the Civil Survey in the 1650s a Protestant Gifford held most of the parish land on the Meath side. In 1642, during the rebellion, the castle was attacked while a Sir J. Gifford held it; in 1661 Thomas Gifford was created the first baronet. The ruin is the physical remnant of their power on this border, long after the De Courcy name had stuck to the place.
Church of Ireland c. 1823, Holy Trinity c. 1840
Two churches and an old graveyard
The Church of Ireland church in the village was built around 1823 (a contemporary account puts it at 1826, costing just over six hundred pounds with a loan from the Board of First Fruits). It is now largely a ruin. The Roman Catholic Church of the Holy Trinity, built around 1840, is still in use and serves the parish. The graveyard on the older church site was in use long before either building went up - some of the grave slabs are said to date back to the sixteenth century, which is the deepest visible thread of continuity in the village.
