Celtic culture refers to the traditions, languages, and social practices of the Celtic peoples, who primarily inhabited regions of Western Europe, including Ireland, Scotland, Wales, Brittany, and parts of Galicia. This culture is characterized by its rich mythology, distinctive art styles, and vibrant music, often featuring instruments like the bagpipe and harp. Celtic languages, such as Irish, Scottish Gaelic, and Welsh, are an essential part of this heritage. The Celts are also known for their intricate metalwork and stone carvings, often adorned with knotwork and animal motifs. Festivals like Beltane and Samhain highlight their connection to nature and the changing seasons.
