The North Cross at Eoghanacht, on Inis Mór, is the kind of ruin that asks you to do a little imaginative reconstruction. A ringed and cusped high cross, a form characteristic of early medieval Irish Christianity in which a circle connects the arms and decorative projections soften the junctions, it has been reduced by time and circumstance to scattered pieces, reassembled in an enclosure that may itself be a relatively recent arrangement rather than anything ancient.

What survives is still worth studying closely. The fragments, which range from around 45 to 80 centimetres in width and 10 to 20 centimetres in thickness, carry decoration that includes knotwork and fret patterns on the shaft, geometric ornament typical of early Christian stonework in Ireland. On the eastern face, scholars have identified what may be a crucifixion scene, though the fragmentation makes certainty difficult. At an original height of roughly 4.2 metres, the cross would have been a considerable landmark in a landscape already shaped by the distinctive limestone terracing of the Burren geology that extends to the islands. The cross sits approximately 80 metres to the north-east of Teampall Bhreacáin, a church ruin that forms the centre of a wider early ecclesiastical complex at Eoghanacht. Scholars including Crawford, writing in 1918, and Waddell in 1981, have both recorded and discussed the fragments, placing the cross within the broader tradition of monumental insular stone carving whose finest examples date from roughly the seventh to the twelfth centuries.
