Dust off those headphones and tune into this classic episode of The Atlas Obscura Podcast, where we visit the crumbled ruins of the world’s largest flour mill—formerly one of Minneapolis’s most prominent graffiti-writing locations, and later a museum.

Our podcast is an audio guide to the world’s wondrous, awe-inspiring, strange places. In under 15 minutes, we’ll take you to an incredible site, and along the way you’ll meet some fascinating people and hear their stories. Join us daily, Monday through Thursday, to explore a new wonder with cofounder Dylan Thuras and a neighborhood of Atlas Obscura reporters.
