The House on the Rock in Spring Green, Wisconsin, is a whimsical architectural marvel built atop a 60-foot rock formation. Famous for its eclectic collections and immersive exhibits, it is home to the world’s largest indoor carousel, featuring over 20,000 lights, 182 chandeliers, and more than 260 handcrafted animals, but not a single horse. #Wisconsin #explorewi #wisconsindells | The Midwest Guide
