Argein is located some 12 km south-west of Saint-Girons just a kilometre west of Audressein. Access to the commune is by the D618 road from Audressein in the east passing through the centre of the commune and the village and continuing west to Aucazein. Apart from the village there is also the hamlet of Viellot. The centre of the commune is the valley of the Bouigane oriented east–west where the village lies. In the valley there is some farmland however the rugged north and south of the commune is heavily forested.[3]
The Buouigane river flows along the central valley east to join the Léz at Audressein. Some tributaries rise in the commune to join the Bouigane including the Ruisseau d'Auriech and the Ruisseau de Sol.[3]
The Parish Church of Saint Peter is an old Romanesque church from the 12th century and now an integral part of a church originally built in the 9th century. The original semicircular Apse forms the south aisle of the present building. There is an altar bearing a very ancient inscription (prior to the 4th century) depicted again in the south wall of the church. The Church contains many items that are registered as historical objects:
A Monumental Painting on the southern exterior facade and interior walls (17th century)[17]
