Morbihan is a department in Brittany, situated in the northwest of France. It is named after the Morbihan, the enclosed sea that is the principal feature of the coastline. It is noted for its Carnac stones. These predate and are more extensive than the ancient Stonehenge monument in Wiltshire, England that is more familiar to English speakers.
Three major military educational facilities are located in Guer, including École Spéciale Militaire de Saint-Cyr, the national military academy for officers.
