Listoghil (Irish: Lios an tSeagail) is the large central monument in the Carrowmore group of prehistoric tombs in County Sligo in Ireland.
Listoghil stands 59m above sea level at the geographic centre of the Cúil Irra Peninsula, c.3 km from Sligo town.
Set close to the highest point in the cluster of monuments, along a low ridge, it acts as the focus of the Carrowmore passage tomb complex.
By the end of the 19th century the tomb had been investigated by antiquarians of the period who recorded finding 'bones of horses', charred wood and a worked flint javelin head.
Some materials from this tomb are in the Alnwick Castle collection[3] In the late 1990s Goran Burenhult, a Swedish archaeologist, partly excavated Listoghil.
A rare example of Irish megalithic art outside of the Boyne valley, consisting of concentric circular carvings, can be seen on the front side of the roof slab (this is visible only in certain lighting conditions).
Sunrise in this position coincides with the start and the end of winter, which are traditionally important seasonal festivals in the Gaelic calendar.
