 It is a relatively protected maritime space constituting a natural shelter for the ships and on the banks of which were established the stations of Port-Jeanne-d'Arc and Port-aux-Français.The gulf of Morbihan is strewn with many islands and islets.It was thus so called by Raymond Rallier du Baty at the time of its forwardings of the beginning of the 20th century in the honour of the Gulf of Morbihan in Brittany (Kerguelen was Breton, and many of the features in the islands have Breton names).
