Knocknashee is part of the Ox Mountain range, formed 300-340 million years ago during the Carboniferous period. It is a table top mountain which, although not as well-known as BenBulben to the north, provides an arresting feature in the landscape of south Sligo. It is the location of one of Ireland’s largest Bronze Age hill forts. At the summit you will find evidence of two cairns which were possibly passage tombs, evidence of the hill’s importance to our ancestors. One of the cairns is located towards the northern end of the hilltop, has a diameter of 28m and a height of 2.5m. The second cairn is located on the northeastern face, 28m in diameter and just 1m in height. There is also some evidence of the outline of the foundations of dwelling structures around the summit.
Exposed rock on the southern face of the hill is known locally as the wishing chair and it is said that if you can see Croagh Patrick on a clear day when you sit in it, your wish will come true. The plateau offers panoramic views of the surrounding landscape, including Keash Hill (17km to the east), the Ox Mountains (6km to the west), Knocknarea (32km to the north) and on a really clear day, Croagh Patrick (80km to the southwest). Just a few kms to the southeast you can clearly see Court Abbey, which is worth a visit. WB Yeats mentions Knocknashee in his poem The Ballad of Fr O’Hart.
