A British artist with a worldwide following has chosen Iowa as the permanent home for his latest work. Andy Goldsworthy has brought in two-hundred-70 tons of eastern Iowa limestone to create four sculptures on the grounds of the Des Moines Art Center.Goldsworthy says it developed into such a huge project because there’s a lack of international awareness of the Des Moines Art Center, which he says should be better known than it is because of its art collection, and for the design of the buildings that house its art work. Goldsworthy is creating three stone walls, each 14-feet-high, and an eight-foot-tall cairn — an egg-shaped sculpture typically built to mark a path or grave.Goldsworthy has built cairns for outdoor sites in San Diego and Long Island, as well as one in Grinnell, Iowa, which he photographed through the changing seasons, as well as during a controlled burn of surrounding vegetation.Goldsworthy’s photographs of the cairns, as well as some of his other work, will be on display at the Des Moines Art Center through October 13th.
