|The enigmatic Stone of Gavea in Rio de Janeiro.|
Between São Conrado and Barra da Tijuca, Rio de Janeiro, a legendary mountain with the face of an ancient giant rises 842 meters above the sea level. When Brazil was discovered, Portuguese explorers gave the rock the name of Gávea, because it was a perfect observatory for in-coming Caravels (the ships used by them to cross the ocean and get to the American continent). But Pedra da Gávea, an enormous rock surrounded by native, exuberant vegetation, has enticed the minds of both the public and historians over the centuries. Its face looks like a carved figure, and there are ancient inscriptions on one of its sides that couldn't possibly have been made by nature. The origins of those carvings have been discussed over the years, but no one can prove who made them and why.
