The earthwork itself, a rath or ringfort, is the kind of early medieval enclosure, typically circular and defined by an earthen bank and ditch, that once served as a farmstead or minor settlement across the Irish countryside. Here, the enclosing bank has been levelled almost entirely, leaving only a slight scarp tracing the original perimeter, but the site's occupation by later religious objects gives it a peculiar afterlife that the eroded earthwork alone would not suggest.

The 1837 Ordnance Survey Fair Plan map recorded it as a clearly defined circular enclosure, annotated simply as 'Clogher Fort', with trees planted both around the perimeter and within the interior, suggesting it was a recognised, perhaps even maintained, feature of the landscape at that time. By the 1924 edition of the OS six-inch map, it was still legible as a circular enclosure measuring approximately 35 metres east to west, with a belfry already noted in the southern quadrant. The site sits on top of a natural rise in grassland, immediately north-east of St. Catherine's Roman Catholic Church, and the townland boundary with Corbrack once ran along its eastern edge, marked by a field fence that appears to have been levelled in recent years. The gradual erosion of both the earthwork and the boundaries around it has made the site harder to read on the ground than the historic maps suggest it once was.

The belfry standing at the centre today, with its cross-slab beneath, gives the place a vaguely ceremonial quality, though whether it was moved here from the nearby church or placed here independently is not recorded. What is visible, if you look carefully across the grass, is the faint curve of the scarp that traces where the original bank once ran, a shadow of the enclosure that the 1837 map captured so clearly.
