Only one still stands upright, rising nearly three metres out of the earth. Together they form a stone row, a type of prehistoric monument consisting of two or more standing stones set in a deliberate linear arrangement, found with some frequency across Cork and Kerry and thought to date broadly to the Bronze Age. What makes Ballindeenisk quietly arresting is precisely this combination of the fallen and the upright; the row has not so much collapsed as partially surrendered, leaving just enough structure to read the original intention.

The alignment runs, or rather ran, on a northeast to southwest axis. The most northeasterly of the prostrate stones is the largest, measuring 3.3 metres by 1.5 metres, and lies roughly three metres from its neighbour, which is slightly thicker at 0.45 metres but somewhat shorter in overall length at 2.8 metres. The single standing stone is positioned 1.4 metres further to the southwest and, at 2.8 metres in height, gives the clearest sense of what the row may once have looked like at full complement. The site was catalogued by Sean O Nualláin in 1988, whose systematic survey of Cork and Kerry stone rows remains the foundational reference for this class of monument in the region.
