Though the castle itself has long since vanished, its footprint remains visible as a subrectangular earthwork, bounded by remnants of earth and stone banks with an outer defensive ditch. The 1654-57 Down Survey map shows a tower house castle standing here alongside a church and medieval roadway, on lands belonging to Edward Nugent, recorded as an ‘Irish papist’. Today, mature trees trace the outline of where this fortification once stood, whilst just 65 metres away sits a motte and bailey, and 75 metres distant lie the ruins of Rathconnel Church and its graveyard.

The castle’s demise appears tied to the construction of Rathconnell Court, a Georgian house built around 50 metres southwest during the 18th century. Local tradition suggests that stone from the castle was quarried away for this new residence, leaving only an irregular scarp along the southwestern side. The Georgian estate itself now lies in ruins between the castle site and the motte, its outhouses and yards still visible. Intriguingly, a small circular castellated tower was built into the northwest corner of the large yard, with its walls incorporated directly into the side of the nearby motte; a peculiar architectural choice that physically connects different eras of the site’s history.

Archaeological surveys from 1970 onwards found no surface remains of the original masonry structure, though the defensive earthworks remain partially intact. The northwest and northeast sides retain their earth and stone banks, whilst the southeast boundary has been reduced to a very slight scarp, disturbed by a modern depression. At the southern corner, a more recent L-shaped bank of earth and stone has been added, though its purpose remains unclear. Despite centuries of quarrying, agricultural use and neglect, the site continues to reveal the complex medieval landscape of Rathconnell, where castle, church and motte once formed a significant power centre in the Moyashel and Magheradernon barony.
