Saint Piran's Flag, a white cross on a black background, is the Cornish national flag. Saint Piran's Day falls on 5 March.
Saint Piran or Pyran (died c. 480), was a 5th-century Cornish abbot and saint, possibly of Irish origin. He is the patron saint of tin-miners, and is also generally regarded as the patron saint of Cornwall, although Saint Michael and Saint Petroc also have some claim to this title.
The consensus of scholarship has identified the "Life" of St Piran as a copy of that of the Irish saint Ciarán of Saigir with the names changed.
