Archaeological evidence suggests this fortification was one of many similar structures that dotted the urban landscape during the Middle Ages, when such towers served as both residences and strongholds for local nobility and merchants. The exact nature of the building remains somewhat mysterious, though historian Gosling's research from the 1980s and early 1990s points to it being a substantial stone structure typical of Irish tower houses from that period.

The castle's demise came around 1747, when it fell victim to a broader campaign of demolition. Lord Limerick, apparently keen to modernise the town or perhaps remove what he saw as obsolete eyesores, ordered the removal of what contemporary accounts described as '18 or 20 ruinous remains of small castles or defensive towers' throughout Dundalk. This systematic clearance swept away centuries of medieval architecture, leaving only archaeological traces and documentary evidence of these once prominent buildings.

Today, nothing visible remains of this particular tower house, its stones likely recycled into later buildings or lost entirely. The site serves as a reminder of Dundalk's medieval past, when the town bristled with defensive structures that spoke to both its prosperity and the uncertain times in which they were built. Archaeological surveys conducted in the 1980s and 1990s have helped piece together this lost landscape, though much about these vanished towers, including their exact locations and original owners, remains tantalisingly out of reach.
