Machu Picchu was built in the classical Inca style, with polished dry-stone walls. Its three primary structures are the "Intihuatana", the "Temple of the Sun", and the "Room of the Three Windows". Most of the outlying buildings have been reconstructed in order to give tourists a better idea of how they originally appeared. By 1976, 30% of Machu Picchu had been restored and restoration continues.
