The Fête de la mer in Cayeux-sur-Mer is a maritime tradition shaped by remembrance and public ritual. The day honours sailors and the coastal community through music, procession and the blessing of the waves. On the Picardy coast, that kind of ceremony keeps the link between town, sea and seafaring work visible to residents and visitors. The event is not simply a seaside celebration; it is a collective gesture of respect for maritime life, local memory and the families whose history is tied to the Baie de Somme.
