"His own evolution at La Ribaute, a former silk factory where Kiefer lived with his family from 1992 to 2007, has spawned an unlikely settlement of structures and pavilions inhabited not by people but by works of art. Spread over almost 100 acres, connected by footbridges and underground passageways, layered like an archaeological dig, the property opened to the public for the first time this year. It is now a permanent exhibit, open annually from May to October."
