Processing’s Photo of the Month — July 2026

Silo Art project, Mankato, Minnesota

Processing’s photo of the month for July is this image I took of the former Ardent Mills grain silos in Mankato, Minnesota. The silos dominate the downtown skyline of the small city, which is situated at the confluence of the Minnesota and Blue Earth Rivers in southern Minnesota. While the photo is not artistic itself, the silos provide the canvas for a monumental mural painted by the Australian artist Guido van Helten, who specializes in painting enormous murals on buildings, silos, and other large structures.

The project was commissioned in 2018 by CityArt, a program of Mankato’s Twin Rivers Council for the Arts and was completed in 2020. The artist was inspired by attending Mankato’s annual Mahkato Wacipi powwow, a gathering to honor Dakota culture, and the mural was designed to “bring together the shared ideals of community, diversity, and inclusion” and “pay respect to history while encouraging a positive dialogue on the future identity of the Mankato area.”

Ardent Mills is the largest flour milling company in the U.S., operating more than 40 locations, including three in Canada and one in Puerto Rico. The company closed the Mankato mill in January of 2025.
