Although Pizarro would eventually make his way to the ancient capital of Cuzco — and to the coastal town of Lima, which he founded — the city of Machu Picchu was so remote that the Spaniards didn't discover it — nor did any other Westerners, until 1911. (Although recent discoveries suggest Pizarro's men may have seen Machu Picchu after all.) Machu Picchu was strategically positioned on the edge of the Incan Empire. It was built at the end of the fifteenth century and is an outstanding example of Incan architecture — a fortress protected naturally by steep slopes and approachable from only one point. It contains 143 buildings, 80 of which were houses. The rest were ceremonial buildings, including temples which housed many mummies — most of them of women.
