It is said that at his death,[note 6] the remains of the Blessed Martin the Abbot which he had brought from Ireland were buried with him at Perranzabuloe.His own remains were subsequently exhumed and redistributed to be venerated in various reliquaries. Exeter Cathedral was reputed to be the possessor of one of his arms, while according to an inventory, St Piran's Old Church, Perranzabuloe, had a reliquary containing his head and also a hearse in which his body was placed for processionals.The churches at Perranuthnoe and Perranarworthal were dedicated to Piran and holy wells at Perranwell and Probus, Cornwall are named after him. In Brittany St. Peran, Loperan and Saint-Perran are also named after him.The earliest documented link to the design of the St Piran's Flag with St Piran is on the coat of arms of the de Saint-Péran or Saint-Pezran (pronounced Peran) family from Cornouaille in Brittany. The earliest evidence known comes from the 15th century, with the arms being De sable à la croix pattée d'argent. (a black shield with a white cross pattée).Mount St. Piran is a mountain in Banff National Park near Lake Louise, Alberta, Canada, named after the saint. St. Piran's crab, Clibanarius erythropus, was also named in his honour, in 2016.
