Aragnouet (in French pronounced as /aʁaɲwɛt/; Occitan (post 1500);: Aranhoet) is a commune in the Hautes-Pyrénées department in southwestern France. It is near with the Spanish border.
The Bielsa tunnel under the Pyrenees connects Aragnouet and Bielsa in Spain. It was first opened in 1976. In 2002, the French government unilaterally decided to close the tunnel to heavy-goods vehicles over 3.5 tonnes, a decision which caused serious concern in Aragon.[2]
