description from Biennale website:
"The on-site artistic works result from a dialogue with nature and the environment. Created in the spirit of a transdisciplinary practice, they are concerned with questioning, exploring and revising the historical term Land Art. as well as transdisciplinary practice. The works constitute proposals for a possible future Land Art which integrates the environment, history and society into its production in addition to landscape and nature. Incorporating the notions of landscape and nature, the created works reimagine Land Art into a practice which integrates the environmental, historical and societal aspects. The artworks of Art Safiental are temporary; they are spread over the length of 25 miles through the Safien Valley starting from Versam at the entrance to the valley, through Tenna and Safien in its middle and to Thalkirch and Turrahus at its end."
