The tallest stone, at the northeastern end, rises to just over two metres, broad-shouldered and thick. Moving along the row, the stones diminish and vary in irregular steps, one barely clearing the ground at fifteen centimetres, another lying prostrate at 2.2 metres long, perhaps toppled, perhaps always intended to lie flat. The spacing between them is uneven, ranging from under a metre to nearly three metres. It is this irregularity, more than any single stone, that gives the alignment its character.

Stone rows, sometimes called stone alignments, are a prehistoric monument type found across Ireland and Britain, most densely in the southwest of Ireland and in Devon and Cornwall. Their purpose remains genuinely uncertain: astronomical orientation, territorial marking, and ritual use connected to burial have all been proposed, and none conclusively established. The Beal Middle row is documented in C. Toal's North Kerry Archaeological Survey, published in 1995, which catalogued this and similar monuments across the region. What the survey also noted is the proximity of the alignment to a circular rath, a type of enclosed farmstead typically dating to the early medieval period, suggesting that this patch of north Kerry pastureland has drawn human attention across very different eras. The rath and the stone row are not contemporary, the rath being many centuries younger, but their nearness to one another is a reminder that monuments accumulate in places that people keep returning to.
