America's Stonehenge is an archaeological site consisting of a number of large rocks and stone structures scattered around roughly 30 acres (120,000 m2) within the town of Salem, New Hampshire in the northeast United States. America's Stonehenge is open to the public for a fee. Part of a recreational area that includes snowshoe trails and an alpaca farm, it is a tourist attraction, with particular appeal to believers in New Age systems.
A number of hypotheses exist as to the origin and purpose of the structures. One viewpoint is a mixture of land-use practices of local farmers in the 18th and 19th centuries and construction of structures by owner William Goodwin in the 1930s. Other claims that the site has pre-Columbian European origins are regarded as controversial, possibly pseudoarchaeological or the result of an early-20th century hoax. Among structures at the site are standing stones that may have been erected to align with astronomical events.
The site was first dubbed Mystery Hill by William Goodwin, an insurance executive who purchased the area in 1937. This was the official name of the site until 1982, when it was renamed "America's Stonehenge", a term coined in a news article in the early 1960s, in an effort to separate it from roadside oddity sites and reinforce the idea that it is an ancient archaeological site. Although the area is named after the archaeological site of Stonehenge in England, there is no cultural connection between the two.(Wikipedia)
