Guido van Helten isn't sure how much surface area there is in eight 135-foot-tall grain silos.
"I know that it's huge," the 33-year-old Australian artist said with a laugh last week in Mankato. "When I came here, I was like, 'Whoa — that's going to be a job.' "
It's a job that's now done, after two years of planning and nearly a year of painting, strapped into a basket lift in all kinds of weather. While a formal celebration will have to wait until after the COVID-19 pandemic has eased, van Helten has finished an artistic task that consumed him.
"It's been everything I've thought about, every day," he said. "I'm very happy. It's a special one."
Using brushes as well as sprayers, van Helten worked in tones of black, white and gray, using industrial paint that absorbs into the concrete and creates a 3-D effect.
The idea of making a canvas of the Ardent Mills silos had been kicking around for years, said Janie Hanson, interim executive director of the Twin Rivers Council for the Arts.
"It's a major downtown entry to Mankato and North Mankato," she said, noting the silos' location on the Minnesota River just off busy Hwy. 169. There was talk of painting them, wrapping them, projecting onto them.
Members of the council noticed van Helten after he painted smaller silo projects in Faulkton, S.D., and Fort Dodge, Iowa. After raising $250,000 privately to fund the work, they invited him to Mankato for the annual Mahkato Wacipi, or Mankato Pow Wow. The yearly gathering honors the 38 Dakota warriors hanged in 1862 by the U.S. government at the end of a brief but bloody uprising. The festival symbolizes reconciliation.
