House on the Rock, near Spring Green in Iowa County, Wisconsin, began as Alex Jordan Jr.'s house atop Deer Shelter Rock and expanded after opening to visitors in 1959 into a sprawling attraction of themed rooms, indoor streets, gardens, and collections. Its most famous elements include the valley-projecting Infinity Room and a vast indoor carousel built in 1981 with hundreds of animals, chandeliers, lights, and mannequin angels but no horses or rides. The attraction is defined by theatrical illusion as much as by collecting, blending genuine antiques with reproductions and fabrications, a practice that drew state scrutiny in 1978. Later expanded under new ownership, it became a singular Wisconsin landmark and a notable presence in popular culture.
