The Historic Sanctuary of Machu Picchu keeps a profound essence of sacred and mystery, which harmonizes with the natural landscape, being a place of great scientific and cultural significance as an expression of architectural development of culture inca. Picchu (Machu Picchu’s original name) was one of these llactas (village), but retained for himself a special role. It was built on land of panaca of Pachacutec (the founder of Tawantinsuyu). It was the most beautiful of the empire because it was built to be the refuge and home of the elite of the aristocracy in the event of a surprise attack. The roads leading to Picchu were forbidden to ordinary people because its location was a military secret. The deep gorges and rugged mountains are the best natural defense.
