In this episode of The Atlas Obscura Podcast, we visit a former limestone mine in Kansas City, Missouri, that has been turned into a 55-million-square-foot industrial park and storage facility.

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.
