Named after Saint Piran, one of the patron saints of Cornwall and of tin miners, the day began as a holiday for, and observed by, Cornish tin miners. The day became a national day in the late 19th Century as a way to celebrate the region in a similar way that other nations do. To celebrate, thousands of people across Cornwall join parades, pasty contests and pirantide events and every town is decked in black and white or black and gold flags.
