Who constructed the stone circles near Salem? Is it possible that the mysterious architects were members of an ancient civilization from across the sea? Did the ancients new more about the world than the modern man imagined?

Mystery Hill was built to last. The stones at the Mystery Hill were not raised by the Pueblo Indians who built cliff houses and brick and masonry homes. To work with brick is easier than with stone. The Pueblo Indians lacked proper tools to work with stones found at the American Stonehenge.

Additionally, if we compare the techniques used to build the pueblos and the ancient structures near Salem, it is clear that the architects were not the same.

Who built Mystery Hill and why?

The architects of Mystery Hill had an impressive knowledge of astronomy. Stone walls throughout the site provide over 200 astronomical alignments with the moon, 45 different stars and important geographic points.

One standing stone points to the star Thuban, which was the North Pole star in 2000 BC. Huge monoliths are aligned to mark the summer and winter sunrise. The stones may have helped those who lived here to plot the seasons.

Although, Mystery Hill is often referred to as America’s Stonehenge, the arrangement of the stones and circles in New Hampshire differ from the original Stonehenge in United Kingdom.

The stones involved in Stonehenge are larger, up to 45 tons. The stones at Mystery Hill are smaller, and the largest is about 11 tons. Stonehenge is located on a plain, not a hill, and is arranged specifically as a series of concentric circles, horseshoes and squares. The stones at Mystery Hill seem scattered around and disordered, and yet the monoliths were raised for a specific reason.

The altar stone, known as the Sacrificial Stone was most likely a place of sacrifice to appeal the gods.
The altar is a 4.5-ton grooved slab and it bears a striking resemblance to altar stones found at megalithic sites in Europe.

Beneath the sacrificial table is the Oracle Chamber. It is an elaborate web of hallways and carved out spaces that are thought to have been used during rituals upon the altar. It contains a bed, bench, closet, and a tube that allows a person inside the lower chamber to speak to congregants above at the altar.

In addition to the Oracle Chamber and the Sacrificial Stone the site has a number of other artificial caves and passages. At least one was constructed with a drain to keep them from being flooded. The purpose of the rest of these structures, except one which appears to be a water well, are unknown.

Solutrean Hypothesis

One possibility is the Solutrean theory.

Dolmens and burial mounds are the place of rebirth akin to Odin sacrificing himself to himself to be reborn. Christianity’s detestation of death and hardship put an end to ancestral worship by closing off the gates to burial mounds and preventing folks from communing with the dead.
