Other organizations in Ireland use the harp, but not always prominently ; these include the National University of Ireland and the associated University College Dublin, and the Gaelic Athletic Association.

The Scottish Gaelic language arrived via Ireland due to the growing influence of the kingdom of Dál Riata from the 6th century onwards and became the dominant language of the southern Hebrides at that time.

Evidence of how Imbolc was celebrated in Gaelic Ireland is found in medieval Irish texts that mention the festival, besides folklore collected during the 19th and early 20th century in rural Ireland and the Scottish Highlands.

Another custom that Lughnasadh shared with the other Gaelic festivals was the lighting of bonfires and visiting of holy wells.
