The Gulf of Morbihan is a natural harbour on the coast of the Département of Morbihan in the south of Brittany, France. This English name is taken from the French version: le golfe du Morbihan. It is more accurately called 'the Morbihan' directly from its Breton name which is Ar Mor Bihan, meaning 'the little sea' (Compare the Welsh y môr bychan), as opposed to the Atlantic Ocean outside, (Ar Mor Bras). Legend says that there are as many islands in the Gulf as there are days of the year. However, this is untrue and the gulf has about 40, depending on the tide. Many islands are private property, except the largest two, l'Île-aux-Moines and l'Île-d'Arz.
