We think of the circular arrangement of stones that make up Stonehenge in England. We may think of ancient South American sites including Machu Picchu or perhaps the enormous, as well as mysterious puzzle of stones that make up the Sacsayhuaman wall in Peru. Or, maybe we think of the ancient Aztec or Mayan civilizations, and the pyramids that are found in Mesoamerica.

But of course, for people that are more familiar with the topic of Lost Ancient Civilizations, essentially people who research it for fun in their spare time… For them, other, lesser known ancient sites may come to mind…

Such as, the 12,000 year old site of Gobekli Tepe in Turkey, the world's oldest known Megalithic site, which is a total mystery.
