Stone spheres of Costa Rica

Originally discovered in the Diquis Delta of Costa Rica, hundreds of polished stone spheres have been found since the 1930s. Their size range from a few centimeters to over two meters in diameter, weighing up to 16 tons. Most are sculpted from granodiorite, an igneous rock similar to granite. Their date of construction is unknown, but it is believed to be between 200 BC and 1600 AD.

Myths

Numerous myths surround the stones, such as they came from Atlantis, or that they were made as such by nature. Another local legend states that the native inhabitants had access to a potion able to soften the rock.

It is wrongly believed that the spheres are perfect. However they do have a surprisingly smooth surface.
