The heirs of Eduardo Chillida have granted permission for a controversial land art initiative by the late Spanish artist to go ahead on Fuerteventura, one of the Canary Islands. The Eduardo Chillida-Pilar Belzunce Foundation has approved the establishment of a new foundation to oversee the project, which involves constructing a 50-metre-high cave inside Mount Tindaya. Local environmentalists protested against the plans in 2011, halting the project. “We have transferred the rights of this project [to a new foundation] with some conditions. These involve respect for artistic and environmental issues,” says Ignacio Chillida, the sculptor’s son.
