Built in 1618 by Sir Hugh Wirrall, this castle passed through notable hands, including Edward Bagshaw, whose name became permanently attached to the site, and later Thomas Richardson. The castle’s exact location has become a matter of some debate amongst historians and archaeologists, adding an intriguing layer of mystery to its already compelling history.

Archaeological surveys have revealed conflicting evidence about where the castle actually stood. Earlier accounts from 1948 documented the survival of a single corner of a building that appeared to have been constructed within a hilltop rath, an ancient Irish ringfort recorded as monument CV010-007 on Ordnance Survey maps. This placement would suggest the castle builders deliberately chose to incorporate or build upon this much older fortification, a practice not uncommon in 17th century Ireland when new settlers often repurposed existing defensive sites.

However, local tradition tells a different story, placing the castle approximately 40 metres east-northeast of the rath. This discrepancy between archaeological interpretation and folk memory highlights how oral history can preserve details that physical evidence might obscure. Today, visitors to the site will find no visible remains at ground level; the castle has completely vanished from the landscape, leaving only its documentary record and the competing theories about its precise location. The Archaeological Inventory of County Cavan, published in 1995 and updated through ongoing research, continues to piece together the fragmentary evidence of this lost stronghold.
