​Machu Picchu

Located in southern Peru , this ruined city lies

on top of a mountain that’s only accessible by

train or a four-day trek. Rediscovered by Hiram

Bingham in 1911, it was an important cultural

center for the Inca civilization but was

abandoned when the Spanish invaded the

region. (It is famously referred to as the “Lost

City of the Incas,” though that is actually

Vilcabamba). The location was made a

UNESCO World Heritage site in 1983, and it

was named one of the New Seven Wonders of

the World in 2007. Concerns over growing

numbers of tourists have led to limitations on

how many people can enter the site, though

only by a fraction of what is necessary.

Hopefully they will limit it even more so this

site can last for hundreds of years more.
