The Arrival of the Celts: As the Bronze Age in Ireland drew to a close, there appeared in Ireland a new cultural influence. Developing in the Alps of central Europe, the Celts spread their culture across modern-day Germany and France and into the Balkans as far as Turkey. They arrived in Britain and Ireland around 500BC and within a few hundred years, Ireland's Bronze Age culture had all but disappeared, and Celtic culture was in place across the entire island. http://www.wesleyjohnston.com/users/ireland/past/pre_norman_history/iron_age .html Lee Ramsey
