Terracotta Warriers


Thousands of terracotta warriors were made and buried over two thousand years ago, but they were only discovered in 1974 when some farmers were digging a well.  They are buried 2-3 meters deep.  They were arranged in a classic large army formation, with the lowest rank soldiers in front, backed by archers and chariots, with the generals in the rear.  This is a unique human creation in the world.
