St Winwaloe was a royal of Cornwall who was brought up in Brittany. He was taught by St Budoc on the Ile Lavret and founded a monastery on a very inhospitable island but was forced to abandon it and found another at of Landevenec just south of Brest.
His disciples founded churches in Cornwall and elsewhere; the large three aisled church on the beach at Gunwalloe on the Lizard is one of them which drew many pilgrims.
