Saint Piran's Flag (Cornish: Baner Peran) is the flag of Cornwall. The earliest known description of the flag, referred to as the Standard of Cornwall, was written in 1838. It is used by all Cornish people as a symbol of their identity.
The flag is attributed to Saint Piran, a 5th-century Cornish abbot. But the white cross and black background design is also the coat of arms of the Saint-Perran (or Saint-Pezran) family from Cornouaille in Brittany, recorded from the 15th century.
