Machu Picchu, Peru

Located on a mountainous area above the Urubamba Valley, Machu Picchu is a pre-Colombian Inca site and regardless of whether you have an interest in history or not, can make you stop and stare in sheer awe.
Built initially in the middle of the 15th century, Machu Picchu was said to have been inhabited for around 100 years before it became uninhabited and went uncovered for over 3 centuries, until Hiriam Bingham, a Yale lecturer, rediscovered the site in July 1911.
