Deep in the North Woods of Wisconsin, some 230 miles north of Milwaukee, sits the world’s largest rotating-globe planetarium.
It’s the brainchild of Frank Kovac, a former paper mill storeroom clerk, who built this roadside attraction in his backyard. Entirely homemade, the project took nearly a decade to complete.
Frank’s planetarium is one of only four of its kind ever built, the oldest dating back nearly 400 years.
At StoryCorps, Frank spoke about how his lifelong fascination with the stars turned into a project of cosmic proportions.
