This 11th century votive chapel is dedicated to the Principality’s and Princely family’s Patron Saint. Sainte-Dévote church was built in the hollow of the “Vallon des Gaumates”, where, during the 4th century a small boat carrying Sainte Dévote’s remains ran aground at its entrance. Every year on 26th January, a boat is burnt at nightfall as part of a traditional ceremony.
