The roughly square enclosure, measuring approximately 34 metres north to south and 32.5 metres east to west, contains headstones but nothing above ground to indicate a building ever stood within its walls. That absence is the quiet puzzle at the centre of the place.

The Ordnance Survey Letters of 1839 recorded the site's Irish name as Teampall Ghlaise Air, translated as Gleshare Church, suggesting a religious foundation old enough to have accumulated a place name of its own by the time surveyors came to write it down. The historian William Carrigan, writing in 1905, noted that the headstones present were all of modern date, implying that any medieval or early modern markers had long since disappeared or never existed in durable form. A visit in 1987 found the graveyard still in active use, though overgrown. The site lies about 100 metres south-east of Glashare Castle, so the two features likely share a historical relationship, the castle and the church serving the same small community in the same stretch of river valley, though the church itself has left no masonry standing to confirm it.
