Inca ceremonial fortress
Sacsayhuaman is one of the most amazing buildings around the world, it is thought that construction began during the government of Pachacutec and continued for another 70 years until Túpac Yupanqui; It is the work of more than 20,000 men who removed stones from the quarries of Muina, Huacoto and Rumicolca and moved 20 km up the hill from the city of Cusco, where they were transformed into the wall that you can see now; and unknowingly, one of the most mysterious places on the planet. The stones of the wall are so well embedded that between them can not be a pin; Is not it amazing? Well then know they are united "for nothing"; any amalgam, glue or any kind of mortar keeps together.
Some studies claim that Sacsayhuaman may have been built by pre-Inca cultures; so, you may be there before the city of Cusco became the capital of the empire of the Incas.
Another of the great enigmas that has the "Sacsayhuaman Fortress" is that it has been discovered that what a sundial is believed, is probably writing 3,000 years old; This rewrite the history of "Sacsayhuaman Inca"
