1. Stonehenge

Of all the world’s famous monuments, none has gained as much of a reputation for pure, simple mystery as Stonehenge. Stonehenge has been inspiring debate among scholars, scientists, and historians since the Middle Ages. Located in the English countryside, the landmark is believed to date back to 2500 BC, and consists of several mammoth pieces of rock arranged and piled on top of one another in what appears at first to be a random design. The site is surrounded by a small, circular ditch, and is flanked by burial mounds on all sides. Although the rock formations that still remain are undoubtedly impressive, it is thought that the modern version of Stonehenge is only a small remnant of a much larger monument that was damaged with the passing of time, and it is largely believed that the building process was so extensive that it could have lasted on and off for anywhere from 1500 to 7000 years.

The Mystery

Stonehenge has become renowned for puzzling even the most brilliant researchers, and over the years the many gaps in the history of its construction, the nature of its use, and the true identity of its builders have become known as “The Mystery of Stonehenge.” The Neolithic people who built the monument left behind no written records, so scientists can only base their theories on the meager evidence that exists at the site. This has led to wild speculation that the monument was left by aliens, or that it was built by some eons-old society of technologically advanced super-humans. All craziness aside, the most common explanation remains that Stonehenge served as some kind of graveyard monument that played a role in the builders’ version of the afterlife, a claim that is backed up by its proximity to several hundred burial mounds. Yet another theory suggests that the site was a place for spiritual healing and the worship of long dead ancestors.
