The castle was recorded in the 1655 Down Survey as one of 'two castles in repaire' in Farbill Barony, and depicted as a tower house belonging to Nicholas Darcy in 1640. Though the castle itself has long since vanished, its memory lingers in the landscape; the site remains visible as a wide, flat-topped rise with subtle hollows and undulations that hint at past disturbance. Local tradition firmly places the castle here, and it may have appeared as a rectangular structure on early Ordnance Survey maps from 1837.

The castle's legacy is preserved through its neighbouring structures, which paint a picture of a once-thriving estate. Just 110 metres east stands Grange Beg House, a handsome five-bay residence dating from the late 17th or early 18th century. The house rises two storeys over a basement with an attic level, its end bays stepping forward with their own lower rooflines. The central doorway features a moulded architrave flanked by narrow sidelights, with similar blocked-up sidelights above at first-floor level. Small attic windows peek from the gables, completing this well-proportioned Georgian composition.

Perhaps the most intriguing survivor is the dovecote, situated about 15 metres from the castle site. This circular pigeon house, built of limestone rubble and lined internally with brick, stands approximately 3.5 metres high with a 7-metre diameter. Though much of the brick lining has collapsed over time, hundreds of nesting boxes remain visible in the walls; testament to its former role in providing fresh meat and eggs for the estate. A doorway on the southeast side once gave access to this remarkable structure, which likely dates from the same period as the house. Together, these buildings offer a fascinating glimpse into the agricultural and domestic arrangements of an Irish gentry estate spanning three centuries.
