December 14, 2025, Tchier de Borée

The Tchier de Borée is a contemporary artwork situated in the heart of the volcanic landscapes of the Boutières region. Created in 2008 by Fabienne Versé and Serge Boyer, this megalithic installation comprises 70 standing stones arranged in a circle 80 meters in diameter. Each stone bears a symbol or message: runes, astrological signs, natural elements (air, water, fire, earth), winds, mythology… The word “Tchier” (from the local dialect) means “pile of stones”: a tribute to stone, time, and the memory of the land. https://www.montagnedardeche.com/patrimoine-culturel/tchier-de-boree-2634/
