According to a marginal note found in an Irish manuscript held at Trinity College Dublin, this castle was dramatically recaptured and rebuilt by Conall O’More, son of David O’More, King of Leix, after wresting it from English control. The same manuscript credits Conall with constructing another castle at a location referred to as Baile atha in roine, which scholars believe may be a scribal error for an Irish rendering of Ballyroan itself.

Historical maps add another layer of intrigue to the site’s identity. On old cartographic representations of Leix and Offaly, Ballyroan appears with the alternative designation of Tolouer, now known as Tullore. This dual naming suggests the area’s complex history of occupation and linguistic evolution as Gaelic and English influences overlapped in medieval Laois.

Today, the only remaining evidence of Ballyroan’s martial past is the motte, or earthen mound, catalogued as monument LA024-006001. While the stone castle that once crowned this artificial hill has completely vanished, the motte itself serves as a reminder of the strategic importance this location once held. The O’Mores, who ruled Leix before the plantation period, clearly valued this site enough to fight for its control and invest in its fortification, making it a key stronghold in their resistance to English expansion into the Irish midlands.
