To the casual eye, the ground at Garraunteefineen presents only a slight, oval rise, easily mistaken for a natural undulation in the wet terrain. But the earth here sits measurably higher than the surrounding field, a remnant of something once substantial enough to be mapped, measured, and recorded as a double-ramparted fort.

The site appears on the 1842 Ordnance Survey six-inch map as a hachured oval enclosure, the hachuring being a cartographic convention used to suggest a raised or scarped edge, roughly 35 metres by 25 metres, positioned to the north of a pond or waterlogged area. By the time the 1905 and 1937 editions of the same map were produced, it was still visible as a raised feature on the north side of a stream and pond. A double-ramparted fort of this kind, essentially a roughly circular or oval earthwork enclosure defended by two concentric banks and ditches, was a relatively ambitious form of construction, suggesting this was once a place of some local significance. Bowman, writing in 1934, recorded the interior as sitting approximately 1.2 metres above the level of the surrounding field, with the full oval measuring around 41 metres by 32 metres, somewhat larger than the earlier map suggested. Even then, almost all of the outer rampart had already been levelled, absorbed back into the agricultural land that surrounds it.

What remains today is subtle. The interior platform still holds its elevation slightly above the field, and the oval outline can be traced if conditions are right, though the boggy ground makes any visit a matter of picking your moment carefully. The outer earthwork is effectively gone, and the inner one survives only as topography rather than as anything a visitor might immediately recognise as a fort.
