Top Mysterious World Landmarks

1. Stonehenge - 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.

2. The Great Sphinx of Giza - Despite its reputation as one of the most famous monuments of antiquity, there is still very little known about the Great Sphinx of Giza. Egyptologists might have a small understanding of why the statue was built, but when, how, and by who is still shrouded in mystery.

3. The Georgia Guidestones - For all their controversy, very little is known about who built the Guidestones or what their true purpose is. R.C. Christian claimed he represented an independent organization when he commissioned the landmark, but neither he nor his group has spoken up since its construction.

4. The Easter Island Moai - While there is a fairly solid consensus on why the Moai were erected, how the islanders did it is still up for debate. The average Moai weighs several tons, and for years scientists were at a loss to describe how the monuments were transported from Rano Raraku, where most of them were constructed, to their various locations around the island.

5. Sacsayhuaman - Most scientists agree that Sacsayhuaman served as a kind of fortress of barrier wall, but this has been disputed. The strange shape and angles of the wall have led some speculate that it may have had a more symbolic function, one example being that the wall, when seen next to Cuzco from above, forms the shape of the head of a Cougar.
