To the naked eye there is little to see, but aerial photography revealed it: a sub-circular cropmark, the kind of ghost that only shows itself from altitude when soil moisture and crop growth betray what lies beneath. It is the signature of an enclosure, roughly 26 metres north to south and 22 metres east to west, pressed into the landscape and largely swallowed by centuries of agricultural improvement.

An enclosure of this kind, defined by a bank and a fosse, was a standard feature of early Irish settlement, typically used to demarcate a dwelling, a farmstead, or a place of some local significance. A fosse is simply a ditch, dug to throw up the material that formed the accompanying bank, and together they created a boundary that was as much symbolic as defensive. At Baptistgrange, the remains of that fosse survive in places, traceable around the north-west, north, and north-east of the circuit, and again to the south-west and west, though worn down to a shallow depression. The scarp, a levelled earthen edge rather than a standing wall, runs in complementary arcs. What makes the site particularly interesting is that it does not stand alone: aerial photography identified it as conjoined to a second enclosure immediately to the south, suggesting this was once part of a paired or compound arrangement, a pattern sometimes associated with expanded settlement or successive phases of occupation. A field boundary now cuts across the monument, and its northern quadrant may actually incorporate the remains of the original bank and fosse within its fabric. The western field boundary has been removed entirely.
