New Hampshire has a rich history. As one of the original colonies, the Granite State was one of the first places that Americans called home. But just how far back does our history stretch? An eerie, spooky archeological site on Mystery Hill in Salem may hold the answer.

Or, America’s Stonehenge may just confuse you more.

Neil Howard/flickr First, let’s introduce it. America’s Stonehenge claims to be one of the oldest man-made sites in North America – over 4,000 years old, to be exact. It’s made up of caverns, rock formations and astrological formations, but no one knows exactly who made it, or why it’s there.

Nikisublime/flickr William Goodwin, who purchased the land in 1937, believed that the site was built by Irish Monks who were fleeing the Vikings in North America. Unfortunately there is no proof that monks or Vikings reached New Hampshire years before Columbus discovered the new world.

Hans Splinter/flickr Most people, however, believed that the site was the work of New Hampshire’s earliest settlers or original Native American inhabitants.

Nikisublime/flickr There are many reports of the site being used to shelter escaped slaves traveling north on the Underground Railroad.
