Kilnasaggart sits in a quiet field a few miles south of Newry, just north of the border. Pilgrims walked this way along the Slighe Mhór, one of the great medieval roads through Ireland, and the stone marks an early Christian cemetery beside the route. Several small cross-slabs lie around the main pillar.
Access is by a short signed lane off the B113. The site is unattended, free, and atmospheric — usually empty, surrounded by cattle, with the Gap of the North as a backdrop. Bring boots if the field is wet.
