The Celts were polytheists, believing in multiple gods and goddesses. Regional deities were known throughout the Celtic regions, and usually included the deities of protection, healing, luck, and honour. Local deities were centered around nature worship, usually a local landscape feature, such as mountains, trees, or rivers.
