The Cornish flag, also known as the Saint Piran's Flag, features a simple design of a white cross on a black background. This flag represents the region of Cornwall in the southwest of England and is associated with Saint Piran, the patron saint of Cornwall. The flag symbolizes the rich cultural heritage and identity of the Cornish people. Adopted officially in 2002, the Cornish flag is widely used during local celebrations and events, such as Cornwall's St Piran's Day on March 5th. It serves as a symbol of pride for many Cornish residents and is often displayed alongside the flags of the United Kingdom and England.
