Located off the coast of Lorient, Groix is a commune in Brittany in north-west France.
The people of Groix are nicknamed Greks, which means "cafetiere" in the Breton language, as in the past women always left coffee heating for the return of their sailor husbands. The island is the second largest island in Brittany, after Belle-Ile, with a surface area of 14.8 sqkm.
A Viking burial, the result of the Norman invasions was discovered on the island in 1906. The island also boasts other sites: the 'Pen Men' and 'Pointe des Chats' lighthouses, several chapels, the prehistoric camp of Kervédan, as well as Port-Lay, particularly interesting because of its small size; it is renowned for being the smallest port in Europe.
