Yangshan Quarry in China is one of this little known places that have remains of very ancient, Atlantean quarries.

What is left in this case are three enormous block of stones that bear the marks of stone cutting machinery or advanced technology. Governments, and in this case the Chinese government, will always try to explain it away as remnants of recent cultures who chiseled away with copper or bronze tools, However, when you look more closely you can see that whoever was quarrying at that location had some power tools at their disposal that could cut stone in ways that are impossible for primitive tools.
