The "Top Secret" attraction in Wisconsin Dells is built as an upside-down house, with its roofline and foundation reversed so the structure appears to stand on its eaves. Admission is advertised at five dollars, billed as a "highly classified experience." The attraction is one of several novelty buildings along the Wisconsin Dells strip designed around optical tricks rather than historical architecture.
