ノルマン語
Due to its comparative isolation, the peninsula is one of the remaining strongholds of the Norman language, and the local dialect is known as Cotentinais. The Norman language poet Côtis-Capel (1915-1986) described the environment of the peninsula, while French language poet Jacques Prévert made his home at Omonville-la-Petite. The painter Jean-François Millet (1814-1875) was also born on the peninsula.
