What remains today is a rectangular earthwork, roughly 20 metres northwest to southeast and 25 metres northeast to southwest, defined by an earthen bank with a shallow external ditch. This modest enclosure marks the spot where a tower house once stood, as recorded on the Down Survey map of 1654;9, which shows the castle on lands belonging to Robert Fitzgerald, described in the records as an ‘Irish Papist’.

By the time of the Down Survey, Laragh Castle was already falling into ruin. The parish terrier noted that there were ‘three Castles in this Parrish lately ruinous’, including Laragh alongside those at Emper and Ballintue. The northwest side of the enclosure has been largely flattened over time, whilst cultivation ridges running northeast to southwest across the interior suggest the site was later repurposed for farming after the castle’s abandonment.

The castle enclosure sits at the heart of a much larger complex of earthworks spanning approximately four hectares. Archaeological features in the surrounding landscape include what appears to be a hollow way running northwest to southeast about 40 metres to the north, and an earthen mound 80 metres to the north;northeast. These features hint at a more extensive medieval settlement that once surrounded the tower house, though much of its original character has been lost to time and agricultural use.
