Arthez-de-Béarn
Arthez-de-Béarn is a commune in the Pyrénées-Atlantiques department in southwestern France.
It took its name from the county of Artois (Artés in Occitan, adapted in French as Arthès or Arthez) like three other communes of France ( Arthez-d'Asson, Arthez-d'Armagnac, and Arthès).
In 1950, -de-Béarn was added to its name to differentiate it from the other Arthès.
