The graveyard at Castledermot in County Kildare contains not one high cross but several, along with a scatter of holed stones and cross slabs spanning roughly seven centuries. That concentration alone sets the place apart, but it is the North Cross that draws the closest attention: a ringed high cross cut from granite, dating to the tenth century, its wheel head decorated with running scroll and key patterns and its shaft and base carrying both figured and ornamental panels.

High crosses of this type, sometimes called ringed or wheel crosses, were a distinctively Irish and Scottish form, the ring thought to have served both a structural and a symbolic purpose. This example stands on a two-stepped pyramidal base, though that base has suffered damage over the centuries. The shaft rises to just over two metres, relatively slender at roughly forty-two centimetres wide, and the figured panels would once have presented narrative scenes to a largely non-literate congregation moving through the monastic enclosure. The site at Castledermot, known in Irish as Diseart Diarmada, was an important early medieval monastery, and the density of carved stonework here reflects that significance. Alongside the North Cross, the graveyard holds further crosses and cross slabs, as well as two holed stones, a category of monument whose precise liturgical or ritual function remains debated among scholars. The cross slabs and grave markers span the tenth through to the seventeenth century, making the graveyard a layered record of how the site continued to function long after the early monastic period.

The crosses stand accessible within the graveyard and can be examined at close range. The key and scroll ornament on the wheel head repays slow looking, as does the transition between the decorative and figured registers on the shaft and base.
