From Machu Pichu an amazing work of architecture to the mysterious caveman buildings in the mountains of Russia. Subscribe to American Eye http://goo.gl/GBphkv 6. Stonehenge One of the most well-known ancient mysteries is the monument of Stonehenge, located in the English county of Wiltshire. This is built in a circle using extremely large rocks standing up vertically and is believed to have been built about 2500 BC. One of the biggest rocks found at this site is about 30 feet tall and weighs about 25 tons. What’s truly strange about this is, the closest place they could have gotten the stone from was a quarry about 20 miles away to the north. People at this time, considered the land to be sacred due to fact the abundance of game meat available here. Many theories are out there trying to explain why it was constructed and acted as a symbol of unification, while others believe it was a religious site. Some claim it was built with ball bearings like you see in this photo. 5. Gobekli Tepe Archaeologists came across a startling discovery six miles from Urfa, an ancient city in southeastern Turkey when they dug up massive carved stones believed to be 11 thousand years old. These were made when mankind had yet to develop metal tools or even pottery. The Smithsonian questions whether or not it’s the world’s oldest temple. It predates stonehenge by about 6,000 years. This location would have been a Mecca for hunters and gatherers at that time, centuries before farming was developed. As they dug deeper, they realized it was arranged in a circle, made of limestone blocks. Using only flint tools workers shaped the stone into pillars before moving them a few hundred yards to the site of the temple. 4.Easter Island Many of us think of Easter Island and a tiny little place in the Pacific off the coast of Chile with mysterious heads sticking out from the ground. You have never known that these mysterious wonders get even more mysterious. These were constructed around the years 1250-1500 BC, by people of Polynesian ancestry. Recent discoveries like you see in this photo, prove that these actually have bodies attached to their heads! As people began to dig deeper, they uncovered that the statues fo much deeper than previously thought. They’ve also exposed carvings on their backs and their meanings have yet to be uncovered. Some believe it represents the traditional tribal of their culture. 3. Bosnian Pyramid Many wouldn’t come to Bosnia and expect to see a pyramid. It’s possibly that because it wasn’t discovered until 2005. If the claims are real, the Bosnian Pyramid would be 25000 years old and the oldest pyramid ever built. Archaeologists are extremely skeptical of this because it defies accepted history. If you take a close look at it, it truly takes the form of a man made structure. Many want these extraordinary claims to be backed up by extraordinary evidence before it is accepted among the archaeology community. If it is real, it does deserve a place on our list. Take a look for yourself and let us know what you think in the comment section. Were there advanced civilizations in this area that we didn’t know of? 2. Machu Picchu This is an incredible work of architecture in the middle of the Andes Mountains and shows what kind of feats the Inca Civilization was capable of. There are a few reasons archaeologists believe it was built. Some claim it was a ceremonial site, a military stronghold or even getaway for the ruling elite. Despite not having advanced warfare technology like some of their foes, they still excelled in knowledge pertaining to agriculture, architecture and astronomy. Many of these well crafted stones cannot even be penetrated with a knife, proving how well the stones fit together. 1.Great Pyramids of Giza There is no other wonder of the ancient world quite as mysterious as the ancient pyramids of Giza. No other monument has created so much intrigue other that these feats of engineering that we still couldn’t reproduce to this day. It’s estimated that there’s a total of 2.3 million limestone blocks that weigh at least 2-30 tons each and is precisely aligned with the constellation of orion. The paste used to combine the stones is from an unknown origin and even with all our technology, we cannot reproduce it’s chemical compound. It remained the world's tallest building for 3,800 years and each side is the same length within 10th’s of an inch. All of this was supposedly constructed without the technology of the the wheel or without metal tool. The quarry used to get the stones was at least 500 miles from the location of Giza. It almost appears as though humans could not have succeeded in completing these structures without help from out of this world.
