cuzco
Cuzco was the capital of Inca. When looked from above, the city looks like the shape of a puma with Sacsayhuman as it's head. This idea was thought out by Pachacutec, one of the greatest emperor of Inca.
There were many colonial building in Cuzco, the Cathedral was built from the stones taken from Sacsayhuman (an important religious location for the Inca). They didn't survive well from the earthquake, most colonial building were destroyed, but the Inca building survived well.
It was doubtful that the local people are faithful to the Catholic religion. There's a painting of the Last Supper in the north eastern corner of the cathedral. But instead of a lamb, the Inca artist put a cuy (guinea pig) at the center of the table. The statue of Marie is also in the shape of an apple representing Pacha Mama (the mother earth).
It used to be the temple of the sun. After the Spanish conquered the Incas, it became the San Domingo Church. They built the church above he structure for the temple of the sun. After the earthquake, some part of the colonial structures collapsed but the original was intact.
Someone did a research, they interpret several holy places in the world which also translate to the meaning of "center of the world" (Cuzco means the naval of the world), and it happens that they can draw a triangle with the Egyptian pyramid at its center.
Standing from one point, you can see through 3 different windows.
The stone work of the Incas (or their sub-contractors from lake Titicaca)
There used to be something very important there but it was missing and no one know what it was. This window points to the original center of the temple.
This part of the gate was made from a single rock.
The moon temple is the counter part of the sun temple (everything is two faced in Inca). So Sun temple is for male (kings) and Moon temple is for female (queens).
There used to be an idol here but it disappeared when the empire ended.
Different techniques for the Incas to join the stones together.
Cuzco was the 2nd largest city in Peru, in the 12th century, it was taken over by the Inca. The Inca is like a brilliant programmer. He did smart programming but he left no documentation (because he didn�t know how to write). Then he was fired by his new boss, the Spanish. And now everything is a big mess because no one understand how he did it. But occasionally people admired his work and claimed that he was doing it with the help of the aliens (or the consultants). Which is quite true, because the Incas were virtual people, they do management without physical participation. They hired consultants from Lake Titicaca (probably the descendants of the Tiahuanaco people) and built all those tricky structures and they sub-contract the Chimu people from the west to do the golden toys. They were conquered but not destroyed because no one can destroy anything that was virtual from the beginning.
