An assortment of over 300 symmetrically round petrospheres have been found scattered around Costa Rica. The spheres range in size from a few centimeters to over 2 meters (6.6 ft) in diameter, and weigh up to 16 short tons (15 t). The spheres were discovered in the 1930s as the United Fruit Company was clearing the jungle for banana plantations. Workmen pushed them aside with bulldozers and heavy equipment, damaging some spheres. Additionally, inspired by stories of hidden gold workmen began to drill holes into the spheres and blow them open with sticks of dynamite. Several of the spheres were destroyed before authorities intervened. Numerous myths surround the stones, such as they came from Atlantis, or that they were made as such by nature. Some local legends state that the native inhabitants had access to a potion able to soften the rock.
