The Mystery Spot was discovered in 1939 by a group of surveyors and opened to the public in 1940. The Mystery Spot has amazed and perplexed hundreds of thousands of visitors from all over the world, and many return time and time again to experience these puzzling variations of gravity, perspective, and height.

"Originally, we wanted to get the level ground below here for a summer home or mountain cabin, but the gentleman we were buying it from would not sell the level ground unless we purchased a strip across the entire south end of his property, including this hillside.

Finally, we bought the entire piece, mainly to get the level ground, and as we were helping the surveyor along the north line, we noted the compass to vary a small amount on the transit and spoke to him about it at that time. He said we might get that variation along a barbed wire fence or some mineral in the ground and let it pass at that.

The official press release by the CALIFORNIA DEPARTMENT OF PARKS AND RECREATION issued on July 30, 2014 reads:

“This roadside attraction established in 1941 is the first and most significant example of its type in California, a "tilt-box" or "gravity house" roadside attraction that gained popularity in the mid-twentieth century. Established by George Prather, the Mystery Spot became a popular roadside attraction under the stewardship of Prather's son Bruce in the late 1940s and 1950s.”
