Celtic heritage refers to the cultural, linguistic, and historical traditions of the Celtic peoples, who primarily inhabited regions of Western Europe, including Ireland, Scotland, Wales, Brittany, and parts of Spain. This heritage is characterized by unique languages, such as Irish Gaelic and Welsh, as well as rich folklore, music, and art that often feature intricate designs and motifs. The Celts are known for their ancient practices, including Druidism, a spiritual belief system that emphasized nature and the importance of the seasons. Their legacy is still evident today in festivals, traditional crafts, and the preservation of Celtic languages, which continue to be spoken and celebrated in various regions.
