China's Stonehenge: Gaizhou Stone Shed, the oldest and largest ground building

When it comes to the megalithic civilization thousands of years ago, the first thing that comes to mind is the Stonehenge in the UK and the huge stone statues on Easter Island in the Pacific. So far, no one knows how the people of that year transported such heavy and huge stones, and then carved and assembled them. The Stonehenge in the UK and the astronomical stars and the angles of sunrise and sunset can all form subtle changes, so that ancient people can observe the image; while the stone statues on Easter Island, people find that their expressions and expressions are exactly the same, facing one direction and watching, and there are also thousands of years ago in Gaizhou, Yingkou, Liaoning, China. Megalithic cultural heritage. Like the Stonehenge in the UK and the stone statues on Easter Island, who built this huge stone shed is still a mystery, so much so that it was previously said to be alien technology, and it can only be speculated that it was built in the late Neolithic or early Bronze Age. And this is also the earliest and largest ground building found in China so far. It is hard to imagine how people mined such heavy stone materials 4,000 years ago or even possibly 6,000 years ago and polished them so smoothly. After thousands of years of wind and sun, you can still see the sharp edges and corners. The stone shed is located on a mountain top, and the nearby area is also a mountainous area with dense forest vegetation, and the nearest natural stone material is at least 20 kilometers away in a straight line. From this, we can see the difficulty of people mining and transporting such large stones at that time. The stone shed is constructed of four large granite slabs that have been processed and polished. The three large slabs supporting the facade lean inward to ensure stability. From this, we can see the superb technology and wisdom of the ancients. The overall direction of the building is 4 degrees east of south. The plane is rectangular. The east, west, and north sides are surrounded by three stone slabs to form three walls, and the top is covered with a large stone slab, and the inside of the wall is paved with stone slabs. The total height is 3.1 meters, the height inside the wall is 2.4 meters, the length from north to south is 2.65 meters, the width at the front is 2.1 meters, and the width at the back is 1.95 meters. The cover stone extends beyond each standing wall on all sides, symmetrical to each other, and the north and south sides extend longer, covering an area of about 50 square meters, and the thickest part of the top stone slab is nearly half a meter! The weight can exceed 60 tons! Although there are no tenons at the junction of the cover stone and the standing wall, the combination is very tight, and it is still well preserved to this day, without sinking and tilting.
