What sets it apart from the general category of prehistoric standing stones is its specificity of form: not a rough pillar or a shapeless boulder, but a rectangular block, measuring 1.42 metres by 0.83 metres at its base and rising 1.55 metres from the ground, oriented deliberately along a northwest to southeast axis.

Standing stones of this kind are scattered across Ireland and are generally associated with the Bronze Age, though in most cases their precise purpose remains unclear. They have been interpreted variously as territorial markers, astronomical alignment points, or ritual monuments associated with burial and landscape. The deliberate orientation of the Trawlebane stone along the northwest to southeast axis is not unusual among Irish examples, and alignments of this kind have long prompted speculation about connections to solar or lunar events, though no specific interpretation has been confirmed for this particular stone. Its position overlooking the Owenashingaun River suggests it was placed with some awareness of the local topography, occupying a vantage point above the water rather than sitting in a hollow or on flat ground.
