A pretty iron bridge, built for farmers at the time. Here the path along the water was in a bad state in April 2026 (a warning was installed on one side of the section, but a detour through the forest is possible).

This is one of the very few straight sections of the canal.

The collection of more than 200 photos for this highlight shows more clearly than words can the diversity of the Breton saints' heaven carved in stone - in this very special case a hill called "Vallée des Saints".

The chapel may have been a lordly foundation from the early years of the 16th century. Its proximity to the Tossen Sant-Veltas fortress suggests that it may have been the private chapel of this castle. This building is said to have been completely finished around 1500 and is a creation of the workshop of Philippe de Beaumanoir, a very active master builder in Trégor. Source: Wikipedia

Located in the heart of Brittany in Carnoët, the Vallée des Saints is a contemporary cultural and artistic site which will host, in 2024, nearly 200 monumental works in Breton granite bearing the effigy of the saints who have left their mark on Brittany. According to legend, Brittany venerates more than 1,000 Breton saints, but only 700 are listed because not all of them are "homologated", that is to say officially recognized by the Roman Catholic Church. It is estimated that there are about 800 saints in Brittany according to the most reserved historians, up to 1,500 for the most optimistic. So there is still a lot to do in the Vallée des Saints.
