The hamlet of Vière, on the banks of the Galèbre river, was the main town of the former municipality of Mariaud, which has been part of Prads-Haute-Bléone since 1973.

Restoration work was carried out in 2010-2011 on the Church of Saint-Etienne (12th century) on the occasion of the production of Richard Nonas's art installation, Edge Stones: Vière and the Highlands.

Richard Nonas, a trained anthropologist, was born in 1936 in the USA and worked in Canada and Mexico before turning his hand to art.

The work in Vière consists of three stone alignments that highlight the natural and social geography of the village and its links with the surrounding hamlets.

It was produced under the aegis of CAIRN Art Centre as part of the VIAPAC cross-border programme, a contemporary Art Route between Digne-les-Bains and Caraglio in Piedmont (Italy).
