Listoghil (Irish: Lios an tSeagail) is the large central monument in the Carrowmore group of prehistoric tombs in County Sligo in Ireland. It was numbered as Carrowmore 51 by George Petrie in 1837 and this designation is still used. Although the district of Knocknarea, Cuil Irra, Cailleach a Bhérra, etc., is steeped in legend, Listoghil has never been satisfactorily connected with the ancient legends in the way that say Newgrange has.
