Inauguration of the Vielha tunnel Historical milestone · Vielha e Mijaran, Val d'Aran, Lleida Image of Vielha e Mijaran, not of the place itself. Inaugurated in 1948 after two decades of works begun in the time of Alfonso XIII, the tunnel under the Vielha pass allowed access to the valley all year round. Its regular use became general in the sixties and transformed the Aranese economy. 1948 Photo: Catalan Art & Architecture Gallery (Josep Bracons) from Barcelona, Catalonia (CC BY-SA 2.0) What to see and do in Vielha e Mijaran
