The castle’s most dramatic moment came during the tumultuous mid-17th century when Sir Philip Percival maintained it during the Confederate Wars, only to see it burned by Irish forces in 1651. By the time Lewis documented the area in 1837, the castle had been incorporated into a dwelling house belonging to a Mr. Rogers, though the original fortification was already beginning to disappear into the fabric of domestic architecture.

The transformation from medieval castle to Victorian residence tells a familiar Irish story of pragmatic recycling. When historian Grove White visited Miss Rogers at Bregogue House in 1909, she revealed that her grandfather had ordered part of the old castle demolished, using the stones to construct what was then the present house. The 1842 Ordnance Survey map shows a house just south of the current location, suggesting the Rogers family rebuilt their home sometime after that date, creating the modest three-bay, two-storey structure with a hipped roof that Grove White photographed at the turn of the 20th century.

Today, no visible traces of the original castle remain, either in the existing house or at the site of its predecessor. The stones that once formed defensive walls now serve as foundations and corners of a family home, their military purpose long forgotten. About 150 metres to the north-northwest, a church and graveyard dating from the same era serve as the only medieval survivors in this quiet corner of north Cork, silent witnesses to the centuries when Bregogue Castle stood guard over this peaceful slope.
