Many consider Coral Castle to be the eighth wonder of the world.  Many associate this place with extraterrestrial intelligence.  Many believe this place defies all logic and science.
Whatever the argument, everyone can agree on one thing about this stone garden...
It is nothing short of miraculous.

Is there a simple explanation?  Or was it some sort of alien intervention?
