The reason most come to Aguas Calientes, or maybe even Peru at all, is Machu Picchu. The world-renowned Incan site, perched high above town amid dramatic mountains, is one of the best ways to appreciate the Quechua people’s greatness, since the Spanish never found or plundered it. The site’s purpose is essentially a mystery, though there are many theories. We may never know if it was an educational center, a military outpost, a religious compound, a preparation ground for youths to be sacrificed, a villa for the ruling Incas, or some combination of them all. Regardless, its magnificence is undeniable, both for its evocative structures and the stunning peaks that form its dramatic 360-degree backdrop.
