America's Stonehenge

What is America's Stonehenge?

Built by a Native American Culture or a migrant European population? No one knows for sure. A maze of man-made chambers, walls and ceremonial meeting places, at over 4,000 years old America's Stonehenge is most likely the oldest man-made construction in the United States.

Like Stonehenge in England, America's Stonehenge was built by ancient people well versed in astronomy and stone construction. It has been determined that the site is an accurate astronomical calendar. It was, and still can be, used to determine specific solar and lunar events of the year.

Various inscriptions have been found throughout the site including Ogham, Phoenician and Iberian Punic Script. Dr. Barry Fell of Harvard University did extensive work on the inscriptions found at the site. They are detailed in his book America B.C.

Frequently Asked Questions

Are pets allowed on the site?
Due to the alpacas that we keep on site, and for insurance reasons, we unfortunately cannot allow even the most well-behaved pets. Please use our lower parking lot to exercise any leashed pets traveling with you. Although there are some shaded areas in our parking lot, it is recommended that you try to leave pets at home on hot days as the tour generally takes at least one hour. Service dogs that have been specifically trained to aid a disabled person may accompany their handler on the tour, provided that they remain leashed at all times.

Is photography allowed at the site?
Yes, photography is permitted for non-commercial use. For further information, please read our photo policy.

What is the trail like?
The trail is on a gradual incline with some uneven rocky terrain. The length of the trail is 1/2 mile, and most visitors spend roughly one hour touring the site.

Is the trail stroller friendly?
For families with small children, we recommend a backpack carrier rather than a stroller.

Is the site handicap accessible?
The visitor center and gift shop are handicap accessible. However, due to uneven and rocky terrain, visitors with mobility restrictions may find the trail to the site to be quite challenging.

Is it a guided tour?
We offer both guided and self-guided tours!
        During the self-guided tour, visitors are shown a twelve-minute introductory video and given maps that explain all the features of the site. The tour guide app can also be downloaded for free on the App Store and the Google Play store, which includes much more detailed information than the paper map, as well as an audio tour.
        Guided tours are offered by appointment. You can reserve your spot by calling us at (603) 893-8300, or emailing us at info@StonehengeUSA.com. Details and pricing for the guided tours can be found here!
