The earthen bank still rises to a height of around 2.35 metres on its outer face, with a broad ditch, or fosse, running around the perimeter at a width of 3.5 metres and a depth of 0.8 metres. That combination of raised bank and sunken outer ditch would once have made this a formidable enclosure, far more than a symbolic boundary.

This is a rath, the most common type of ringfort found across Ireland, a circular earthen enclosure typically dating from the early medieval period, roughly the fifth to the twelfth centuries, and most often associated with a single farming family of some local standing. They were homesteads rather than fortresses, though the bank and fosse provided real protection against cattle raiders and opportunistic threats. The Pallas example, surveyed by Denis Power and recorded in 2011, measures approximately 42 metres in diameter across its interior, placing it firmly within the middle range of such structures. One detail distinguishes it from many overgrown or collapsed examples in the region: the interior is level, dry, and clear of overgrowth, making its geometry unusually legible. There is also evidence of more recent human interference; the inner face of the bank has been modified to create a near-vertical profile running from the south-east around to north-north-west, suggesting agricultural or land management work carried out at some point after its original construction.

Access to the site is via the surrounding pasture, so landowner permission is advisable before visiting. The gap in the bank on the south-south-west side, roughly 3.6 metres wide, is likely the original entrance, a common feature of raths and worth looking for deliberately. Because the interior is open and unobstructed, the full circuit of the bank can be walked and appreciated without difficulty. The fosse, though reduced from its original depth, remains visible as a clear depression around the outer edge. A dry day in late autumn or winter, when vegetation is low and the earthworks cast longer shadows, gives the clearest sense of the structure's original scale.
