Saint Cadou
Highlight • Other
Notably on Cado Island in Morbihan, where the founder of Llan-Carvan Abbey in Wales is said to have ended his life as a hermit on a tiny island around 577 AD.
In any case, this village and this church bear his name.

Sizun
Highlight • Other
Sizun has his destiny linked to one of the most resounding criminal cases in Brittany and which has so far never been elucidated and which continues to make headlines. This is the Seznec affair: In May 1923, following the disappearance of the businessman and general councilor of the canton of Sizun Pierre Quéméneur, his associate Guillaume Seznec was accused of having killed him and having made his body disappear and condemned by the Assize Court of Quimper to hard labor for life and deported to Guyana, to Devil's Island. His grandson Denis Seznec has devoted his life to fighting for the rehabilitation of his grandfather, but has not succeeded so far.
