Slievecallan

Slievecallan or Slieve Callan (), also historically called 'Mount Callan', is a mountain with a height of in west County Clare, Ireland. It is the third highest mountain in the county. There is a small lake and two megalithic tombs on the south side, and traditionally the mountain was used for Lughnasa gatherings.

== Archaeology == On the south side of the mountain, in the townland of Knockalassa, are the remains of two megalithic tombs; one on the mountainside and one further down by the Ennis Road. Irish folklore holds that it is bad luck to damage or disrespect such tombs and that deliberately doing so could bring a curse. An ogham stone was found in the late 18th century in the same area. It was the first ogham inscription to be translated and published. The inscription claims to mark the grave of Conán, one of the fianna of Irish mythology. Charles Vallancey and Theophilus O'Flanagan published what they claimed was a poem from the medieval tale Cath Gabhra, which says that Conán was slain at Slievecallan during a ceremony to worship the sun. Michael Comyn wrote that people would gather on the mountainside, at Buaile na Gréine ("summer pasture of the Sun"), where they would sacrifice livestock to the Sun at a stone altar. A small lake on the mountainside is called Lough Boolynagreana. However, it is now accepted that the ogham stone was carved shortly before its discovery, and the Cath Gabhra poem is not found in the original. Nevertheless, the stone fueled antiquarian fieldwork and the study of ogham.
