#18 The Stone Spheres Of Costa Rica
Mysterious and mind-boggling creations of the stone spheres of Costa Rica were made by civilizations that existed between 700 CE and 1530 CE. The workers of the United Fruit Company were clearing the land in Diquís Valley of Costa Rica in 1930. They unearthed a large number of enormous man-made balls.
The biggest of the sphere was as big as 16 tons in weight and over two meters in diameter. Eventually, these stones were relocated in different places, 6 being in the courtyard of Costa Rica’s National Museum in San Jose and some are now famously priced lawn ornaments.
