This is an isle out of the world, out of time. That is a unique place, isolated in its gang of reefs and its vapour of spray of seawater, which used to be submerged by the ocean. Man has been clinging to this isle like a limpet since the prehistory, as if he was protected from the rest of the world thanks to its wild environnment.
Situated in the entrance of the Channel and inevitable passage of the shipping lanes, Sein has been famous first for its wreckers and then for its rescuers.
The coast abounds with reefs and wrecks, and the lighthouses of Sein and Ar Men guide the vessels with their reassuring beams of light.
Contrary to this imposing nature, the human presence gets noticed because of its generosity and solidarity.
The history is there to remind us of the 700 shipwrecked men who were welcomed in 1796 on an isle which was a prey to the scarcity, or the embarkation of 150 seamen and fishermen for Great Britain at the time of General De Gaulle's appeal to the French nation. In order to fight in the face of adversity, the inhabitants of Sein called " S nans " stick together, as their white houses with coloured shutters are huddled around narrow alleys.

Among other sights of Sein, people can still pass a few women who wear the " Jibilinenn ", a black mourning headdress which was adopted in 1886 at the time of the last epidemic of cholera. It is to be noted that the isle is exempt from land tax, which is a thin compensation for the roughness of the island life. The proverb says : " who sees Sein sees his end ". Go there fearlessly, you will find authenticity.
