Overview
Castle Rag is a small ruined medieval tower house in Jigginstown, on the outskirts of Naas. It stands in pasture to the west of Jigginstown Castle and is one of the lesser-known fortified buildings in the area.
Although compact, Castle Rag is an impressive survival. It is described as a rectangular tower house, surviving to about three storeys, with a vaulted ground-floor chamber, an upper chamber with a fireplace, battlements above, and a projecting turret at the north-east corner.
Why it matters
Castle Rag is part of the medieval defensive landscape around Naas. Tower houses like this were fortified residences, often built in the 15th century, and were common around the edge of the Pale, the area of English control centred on Dublin.
The castle is also connected with the wider Jigginstown heritage landscape. Nearby are Jigginstown Castle, the medieval gatehouse, Limerick Bridge and other historic structures, making this part of Naas especially rich in layered architectural history. Kildare County Council records Castle Rag as RPS NS19-079, describing it as a ruined tower house in pasture west of Jigginstown Castle.
What to notice
Look for the castle’s compact rectangular form, thick stone walls and surviving height. The building is small compared with Jigginstown Castle nearby, but it is older and represents a very different type of defensive architecture.
Descriptions of the site note a vaulted ground floor, first-floor living space, fireplace, battlements and a projecting stair turret. These features show how a tower house combined defence, status and domestic use in one compact structure.
