Today, almost none of that is visible. What survives above ground amounts to little more than a large open space marked on Ordnance Survey maps as a Fair Green, and the faint suggestion that something more substantial once stood here.

The settlement's name is thought to derive from Gleann Ogra, meaning Ogra's glen, a pre-Norman designation that hints at an older layer of occupation before the borough ever took shape. After the Norman conquest, Glenogra was granted to William de Burgh, and by the later thirteenth century it had passed to the Desmond Geraldines. A document drawn up in 1298 on the death of Thomas FitzMaurice records the extent of the manor in some detail: the burgesses of Glenogra held six carucates of land, a carucate being roughly the area one plough team could work in a year, and paid 119 shillings and sixpence annually in rent. That is one of the last clear administrative snapshots we have. The Civil Survey of 1654 to 1656 tells us that Henry, Earl of Bath, then held the site, on which there remained a castle and bawn, the bawn being an enclosed courtyard or defensive wall surrounding a tower house, along with thirty houses and cabins, a mill, and even a court leet and court baron, both local judicial institutions. Beyond that, the documentary record goes quiet. Glenogra likely persisted in some form as long as the Desmond earls held sway, but the collapse of that earldom in the sixteenth century seems to have taken the borough with it. No earthwork features survive today, and attempts to identify nearby medieval remains at Caherguillamore as part of the same settlement are considered unlikely given the distance from the castle and church sites.

The former castle and church sites carry their own Ordnance Survey record numbers and can be located on the mapped landscape east of Croom, though there is little to see at ground level. The Fair Green to the south of the castle site is perhaps the most legible remnant of the borough's economy; fairs were essential to medieval town life, and this open area may well have served as the market place long after the borough itself had ceased to function. Aerial photographs taken in 2002 are held in the Archaeological Survey of Ireland archive and may offer a clearer sense of the site's layout than a visit on foot.
