America's Stonehenge is an ancient site, a maze of walls, chambers and ceremonial places located in the woods north from Salem – a legendary place. Nobody knows who built that ancient infrastructure. May be it was built by Native Americans or maybe from early European migrants. America's Stonehenge is over 4000 years old and is the oldest human made structure in North America.
