A great house on the edge of an older fort
Castle Caulfield is said to have been built between about 1611 and 1619 by Sir Toby Caulfeild, an English planter who was granted these lands in the wake of the Plantation of Ulster. What he raised was less a castle and more a grand Jacobean manor house — a fashionable, comfortable great house with tall rows of mullioned windows, meant to show status rather than to hold off an army. It's thought to stand on the site of an earlier stronghold of the O'Donnelly family, whose fort once commanded the same ground, and the surviving gatehouse is believed to belong to that older phase.
The house didn't have an easy life. It's said to have been damaged in the rising of 1641, patched up and lived in again, then finally abandoned and left to fall into the handsome ruin you see today. Local tradition adds a couple of famous names to the story: both St Oliver Plunkett and, later, the Methodist founder John Wesley are said to have preached here at Castle Caulfield in their day — colourful claims worth taking with the usual pinch of salt, but they hint at how much life once passed through these walls.
Standing in the roofless shell now, with the village going about its day just beyond the wall, it's an easy place to picture: a proud new house rising over an old Gaelic fort, at the very moment the whole shape of Ulster was being redrawn.
