Museo del Valle de Arán, Regional history museum in Vielha e Mijaran, Spain.

The Museo del Valle de Arán occupies a stone manor house with wooden details that holds objects documenting the region's past. The building contains exhibition spaces alongside research and storage areas for ongoing curatorial work.

The museum was founded in 1983 by an agreement between Aran Valley municipalities, the Diocese of Urgell, the Catalan government's culture department and the Aran Valley Ethnological Museum Foundation, created in 1973. It is housed in the late Gothic Tor deth Generau Martinhon in Vielha and also occupies Casa Joanchiquet in Vilamòs and the church of Sant Joan d'Arties. Since 1992 it has been managed by the Conselh Generau d'Aran.

The rooms display everyday objects and traditional tools that shaped daily life in the valley. Photographs show how local people lived and worked over generations.

The museum is reached through the manor house in central Vielha and is easy to locate on foot. Calling ahead is recommended to arrange group visits or guided tours and confirm opening times.

On the third floor stands the 18th-century armari des Privilègis, an cupboard from the parish church of Sant Miquel in Vielha that held the documents of the Conselh Generau. Inside it was found Era Querimònia, the charter of privileges of the Aran Valley. The same room keeps utensils and garments worn by members of the old council.
