Overview
Fifteen kings of Fermanagh were crowned on a low grass mound in this townland, the last of them in 1589. The mound is Sliabh Gabhra, the inauguration place of the Maguires (Mag Uidhir), the Gaelic dynasty that ruled Fermanagh from the late 13th century until the kingdom collapsed in 1607. Their capital was at nearby Lisnaskea; this hill, a couple of kilometres west, is where each new chief was made.
Set your expectations first. Cornashee is open farmland, not an attraction. There is no car park, no path, no sign, and the mound itself is unspectacular to look at after centuries of grazing have rounded it off. What you are standing on, not what you can see, is the whole point of coming.
Sliabh Gabhra
The mound is a large burial cairn sitting inside a round enclosure, almost certainly a Neolithic tomb that was reused, thousands of years later, as a royal stage. It is a scheduled monument, and geophysical surveys using magnetometry have confirmed it as a medieval inauguration site rather than just local tradition. You will also see it written as Sgiath Gabhra or Sciath Gabhra, and it is known locally as the Moat Ring.
Fifteen Maguire kings were inaugurated here between 1264 and 1589. The ceremony made a chief in the open air, in front of his assembled people, on ground that linked him to the land and the dead beneath it. According to one Maguire historian, signal fires were set ablaze on the mound to mark each inauguration. The townland name, Cornashee, has been read as ‘hill of the fairy mound’ – an older layer of belief sitting under the political one.
Visiting
This is a self-guided stop and a short one. There are no facilities of any kind: no toilets, no shop, no café, no marked walk. Bring whatever you need and take it away again. The field is exposed and the ground turns muddy after rain, so wear boots and a waterproof.
The site sits on private farmland, so respect boundaries, keep any dogs on a lead near livestock, and leave gates as you found them. If you only have a passing interest in archaeology, Cornashee on its own will not fill an afternoon. It earns its place as a quiet ten minutes paired with Aghalurcher, the early church ruins and graveyard a few kilometres east, where there is rather more to look at.
Getting there
Cornashee lies in the barony of Magherastephana, in the civil parish of Aghalurcher, just west of Lisnaskea. Reach it by car from the town, heading west on the Aghalurcher road and onto the narrow rural lanes near the hill. There is no public transport to the site, so a car or local taxi is the only practical option. Go on a clear day: the rise gives a long view over Lisnaskea and the Lough Erne basin, which is reason enough to time it well.
