Machu Picchu : Lost City of the Incas
Machu Picchu (also spelt Piccu), the Lost City of the Incas, was discovered by American Professor Hiram Bingham during his search for the lost city of Vilcabamba. With the help of an old document about Manco Capac the 2nd, an innkeeper and a 10 year old boy, he found the brilliant ruins of Machu Picchu on the 24th of July 1911.
To Note: Not much is known about the written language of the Inca due to the evidence destroyed by the Spaniards in the name of religion and bounty hunting. What historians have managed to piece together from various oral traditions and post-Conquest reports is that they... well...had a calendar. Cuzco, the Navel of the World, was their capital in Peru, and the Sapa Inca, the highest ranking Inca, took his authority from the sky. Tahuantinsuyu, as they called their capital, means the land of 4 quarters, and was divided according to the intercardinal directions of northeast, northwest, southeast and southwest. They built shrines called huacas and ceques (lines connecting the huacas).There are many astronomical alignments along the ceques, with some of them lining up with solstice sunsets and sunrises. Not only were did the Inca exhibit their astronomical knowledge at Cuzco, they also showed it at other sites they built.
