Osaka Castle Megaliths: Lost High-Tech or Human Ingenuity?

How did ancient Japanese cut these massive granite stones, transport and position them on the construction site 400 years ago? Were these huge stone blocks produced by lost advanced ancient high-tech or human skills? Here are my findings. #alternativehistory #lostcivilizations #megalithic #osaka Patreon:   / curiousbeing   www.buymeacoffee.com/curiousbeing Instagram: instagram.com/curiousbeingtina Twitter:   / curiousbeing15   In this video I discuss the massive stone blocks at the Osaka castle in Japan. The original Osaka castle was built in the late 16th century. It was destroyed during the war and then rebuilt under the new ruling shogun Tokugawa Ieyasu in the 1620s. The present-day castle with its awe-inspiring megaliths were documented to be constructed and installed during the decade-long reconstruction in the first half of the 17th century. Among these huge stone blocks, the octopus stone is the largest and most famous. It measures 5.5×11.7 meters (18’x38’) and is estimated to weigh about 108 tons. There are at least 10 such big megaliths at the Osaka castle. I did some research and found that there are other mysteries and lesser-known facts about these impressive Osaka megaliths which shine a light on how they were quarried, shaped and transported.
