A surviving concrete airship hangar in the Cotentin, preserved as a civil heritage attraction with a museum and visitor activities. Interpretation follows the site’s naval aviation origins and later history. The former military property now belongs to the Communauté d’Agglomération du Cotentin and is administered by the Association des Amis du Hangar à Dirigeables d’Écausseville. This record represents the visitor site, rather than its association’s mailing office in Montebourg.
