Carn Clonhugh 1.73

Corn Hill, also called Carn Hill or Carn Clonhugh, is a hill in County Longford, Republic of Ireland. It lies north of Longford, between Drumlish and Ballinalee, in the parish of Killoe. At 278 metres above sea level, it is the highest hill in the county and has a television mast on the top which rises 123 metres above the peak of the hill.EtymologyThe hill was anciently called Sliabh Uillinn and later Sliabh Cairpre after the Cairpre Gabra. The name Carn Clonhugh is an anglicisation of the Irish Carn Clainne Aodha, meaning "cairn of Clann Aodha" (anglicised "Clanhugh"). Clanhugh was a historic territory in the northwest of County Longford. The earliest cartographic reference to the hill is found in the 1837–1842 Ordnance Survey Ireland 6 Inch map, which can be seen on the Ordnance Survey Ireland website. In cartography, the hill was referred to as Carn Clonhugh, but by the time of the 2nd edition 1887–1913 Ordnance Survey Ireland 25 Inch map, that was replaced with Corn (corruption of Cairn) Hill. Today, it is known locally as Corn Hill.GeologyCairn Hill is located in area of north Longford dominated by Middle to Upper Ordovician slate, sandstone, conglomerate and greywacke according to the Geological Survey of Ireland public data viewer.
