Exploring magical Machu Picchu

Peru has been on my travel wish list for many years now, for one prime reason: the magical, mysterious ruins of Machu Picchu.

Since it came to international prominence in the early 20th Century, this legendary Incan site has been the subject of much speculation: what it was used for, how it was never discovered by the conquistadors, why it was deserted - and how on earth each perfectly shaped stone was crafted so that the buildings hold together without mortar: a feat of engineering lost with the Incans themselves. 

Here, I explore not only the stunning site itself, high up in the Andes Mountains, but also the rich history and uncertain future of this jaw-dropping attraction.
