25. The Stone Spheres of Costa Rica
Just like the Egyptian pyramids and The Stonehenge, the Diquis stone spheres of Costa Rica are quite mysterious in their origin and purpose. These Pre-Columbian artifacts are found in various sizes and are always perfectly spherical in shape.
But get this – each sphere has been carved out of granite and sedimentary stone and Andesite, but there are no nearby sources for these materials around the spheres’ location! So likely they were transported over massive distances. But for what? Some say these were road markers or spiritual markers for the afterlife.
