Machu Picchu is the most precious treasure of the Inca Empire and one of the most impressive archaeological sites on the planet. Built in the mid-15th century, this stone citadel is a masterpiece of engineering and astronomy, harmoniously integrated into an environment of high jungle and steep peaks. Declared a World Heritage Site by UNESCO, it offers an unparalleled spiritual and visual experience, where clouds often caress the agricultural terraces and sacred temples, keeping alive the mystery of its original purpose.
