The site appears as little more than a faint rectangular outline on the 1839 Ordnance Survey map, measuring roughly 20 metres northeast to southwest and 10 metres northwest to southeast. Today, nothing remains visible at ground level in the pasture where the structure once stood, positioned at the head of a small valley on a gentle southeast-facing slope.

The castle’s history remains somewhat mysterious. The Civil Survey of 1654-56 records that Dermot McDowling Cavanagh, an Irish Catholic, owned five hundred acres at Ballendone in 1641, though curiously, no castle is mentioned in these documents. This absence from the historical record raises questions about when the structure was built and when it fell into ruin. By the time the Ordnance Survey mapped the area in 1839, it was already marked simply as ‘Site of Castle’, suggesting the building had been gone for some considerable time.

The location sits on fairly level ground, with a ringfort approximately 120 metres to the northwest, indicating this area held strategic or settlement importance over different periods. While the castle itself has vanished, leaving only its ghostly footprint on old maps, its proximity to other archaeological features suggests Ballindoney was once a more substantial settlement than the quiet pastureland that exists today.
