“Did the gods play golf here?” you may ask yourself if you take a holiday to Costa Rica. Strange hard stone balls are found everywhere. The whole country is littered with them. They seem randomly distributed but with bird’s eye view one discovers patterns believed to be the mirroring of certain constellations. The stone balls are made of hard rock, often granite, and have true spherical shape in most cases. There are small ones but the bigger balls are larger than 2 metres in diameter and weigh many tons.

However, many of the balls have been removed from their original positions and taken to gardens and public parks for decoration purposes. So it's virtually impossible to examine the original collective alignment. Furthermore, many of the stone balls were demolished in search of treasure as it was believed that they contained gold or other valuables.

The scattered balls resemble the jars of Laos which have similar sizes and are also distributed over a large area. Who made these balls? How did they make near perfect spheres? The period dusirng which they were made is also unknown.
