The day, which was actually yesterday March 5, is the national day of Cornwall, a tradition inspired by the legend of St Piran.

St Piran was the patron saint of tin and the holiday began as a celebration observed only by tin miners.

Legend tells of Piran’s arrival in Cornwall from Ireland during the 5th century.

After a disagreement with King Aengus of Munster, Piran was tied to a millstone and thrown off the Irish cliffs into a stormy sea.

The sea became calm and the millstone miraculously floated and brought him to Cornwall, where he washed up on Perranporth beach.

He spoke only Irish and the locals spoke only Cornish but he still gathered disciples. A badger, a fox and a boar were his first disciples, according to legend.

Penhale Sands is believed to be the original landing site of Saint Piran.

Dating back to the 6th century, St Piran's Oratory is also thought to be one of the oldest Christian sites in Britain.

The remains were discovered in the late 18th century, and in 2014 the covering sand was removed to reveal a building more than a thousand years old, in a reasonable state of preservation.
