Today, the field at Tullynagrow shows only pasture. Whatever once stood here has left no trace that can be seen at ground level.

The cartographic history of the site tells a story of gradual uncertainty. The 1834 map labels it a "Druid's Circle", a term that belongs to an era when antiquarians attributed virtually any megalithic arrangement to pre-Christian ritual practice. By 1907, a revised edition of the map had reclassified it as a "Cromlech", a word used loosely to describe a variety of prehistoric stone monuments. The Ordnance Survey Memoirs, compiled in the nineteenth century as a wide-ranging record of Irish parishes, noted only "the partial remains of a Druidical Circle the extent of which cannot be traced", suggesting that even at that early stage the site was already fragmentary and difficult to interpret. E.P. Shirley, writing in 1879, was blunter still, describing what remained simply as "some standing-stones". The progression from gothic-lettered circle to anonymous stones to bare pasture is a common enough fate for prehistoric monuments in an agricultural landscape, where centuries of ploughing, stone clearance, and land improvement gradually absorb whatever once gave a place its distinctive shape.
