House on the Rock
Resting atop a 60-foot stone formation in Spring Green, Wisconsin, the House on the Rock is one of the best-known architectural oddities in the United States. Built by eccentric artist Alex Jordan in the 1940s, the House on the Rock was his vacation home before being turned into a museum in 1961. Jordan sold the building in the early 1980s, but it continues to grow as a tourist attraction.
With 14 unique and lavishly decorated rooms - including the Infinity Room, with 3,264 windows -- and a surrounding complex that houses a miniature circus and the world's largest carousel, the House on the Rock is at once wacky, tacky, innovative, and elegant.
