No list of lost cities is complete without Machu Picchu. This old Inca
city sits on a peak in the Andes. It was only inhabited for a short
period of time, likely 1450-1572 AD, before being abandoned as a result
of the Spanish conquest of South America. Since Spaniards never found
the city, and locals did not reveal its location, Machu Picchu only came
to the attention of the West in the early 20th century. Debate still
exists as to whether Machu Picchu was a regular settlement, a Royal
retreat, or a religious sanctuary. To reach the site itself is now
incredibly easy, with regular buses and trains. This has led to worries
about the sustainability of large numbers of visitors there. However,
given the wonderful views and the ruins themselves it is easy to see why
people flock to Machu Picchu.
