Asasp-Arros is located 6 km south ofOloron-Sainte-Marie on the left bank of theGave d'Aspe and straddling the old royal route built byLouis XIV toCanfranc inSpain.[3] The commune consists of two portions joined by a narrow neck of land just south-west ofLurbe-Saint-Christau. Access to the commune is byRoute nationale N134 (European route E7) fromGurmençon in the north passing through the length of the commune and the village and continuing toSarrance in the south. The D918 road comes fromIssor in the west then goes east from the village over the mountains toArudy. The southern portion of the commune is heavily forested with few farms while the northern also has extensive forests but with about 40% of the land area farmland.[4]
Confluence of theGave d'Aspe and the Gave de Lourdios
The commune is part of theDrainage basin of theAdour with theGave d'Aspe forming its entire eastern border as it flows north to join theGave d'Oloron atOloron-Sainte-Marie. Many tributaries flow into the Gave d'Aspe in the commune. From south to north these are: the Soum de Bordettes, the Ruisseau des Cournales, the Ruisseau de Labatnere, the Gave de Lourdios at the neck of the commune, and the Ruisseau Toupiette. In the west of the commune the Mielle river flows north with several tributaries rising in the commune: the Arrec de Bernet, the Arrec de Termy, the Arrec de Cazaux, and the Arrec de Sarraude. The Mielle continues north to join theGave d'Oloron south-east ofMoumour.[4]
According toMichel Grosclaude,[16]Arros comes from the basque radical(h)arr ("stone") or from a former owner calledArro, in each of the two possibilities expanded by the Aquitaine suffix-ossum, giving "place of stone" or "Domain of Arro".
From 1956 until 1971 (the date of merging with Asasp)Arros was calledArros-d'Oloron[3] to differentiate it fromArros-de-Nay.
On 1 January 1973 (Prefectorial Order of 29 December 1972),[3] the commune of Arros-d'Oloron (called Arros until 1956) was merged with Asasp to form the new commune of Asasp-Arros.[28]
The main activity is agriculture (livestock, pasturage, polyculture). The commune is in theAppellation d'origine contrôlée (AOC) zone ofOssau-iraty. The quality of the water from the rivers allows development ofFish farming.
A Hydro-electric power station has been built at the confluence of theGave d'Aspe and the Gave de Lourdios.[3]
Until 1494[3] there was a dyke on thegave d'Aspe which linkedLurbe toAsasp. It was then replaced with a bridge, making the village an important stage on a secondary way on thevia Podiensis (orPuy Route), one of the modern paths on theWay of St. James.
A large wooded area,[42] with many hiking trails extends over the commune.
